Local resistance to Lomiko Metals’ Outaouais graphite mine

Leave a reply

It’s been a while since BC-based Lomiko Metals has rated more than a passing mention here. Back in June 2024 the company experienced a rough patch regarding their plans to mine for graphite in one of their Québec mines, from a June 9, 2024 article by Joe Bongiorno for Canadian Broadcasting Corporation (CBC) news online,

In Quebec’s Laurentians region, a few kilometres from a wildlife reserve and just outside the town of Duhamel, lies a source of one of the world’s most sought after minerals for manufacturing electric vehicle batteries: graphite.

Since Lomiko Metals Inc., a mining company based in Surrey, B.C., announced plans to build a graphite mine in the area, some residents living nearby have protested the project, fearing the potential harm to the environment.

But opposition has only gained steam after locals found out last month that the [US] Pentagon is involved in the project.

In May, Lomiko announced it received a grant of $11.4 million from the U.S. Department of Defence and another $4.9 million from Natural Resources Canada to study the conversion of graphite into battery-grade material for powering electric vehicles.

In its own announcement, the Pentagon said Lomiko’s graphite will bolster North American energy supply chains and be used for “defence applications,” words that make Duhamel resident Louis Saint-Hilaire uneasy.

…

Depending on how you view things, this is either good news for bad news in a September 17, 2024 news item on CBC news online, Note: Links have been removed,

Two Quebec cabinet ministers say the province will not fund a proposed graphite mine north of Gatineau because it doesn’t meet the government’s standards for local support.

B.C.-based Lomiko Metals has been testing samples from its La Loutre site near the town of Duhamel, which the company says on its project website has shown “excellent graphite properties” for making batteries.

Many nearby residents have been against the proposal for years due to a perceived threat to outdoor recreation and associated businesses. No environmental assessment of the site has been conducted.

La Loutre has drawn funding from the Canadian and American governments for its potential role in the switch from gas to electric vehicles and related drop in fossil fuel emissions, but Minister Responsible for the Outaouais Region Mathieu Lacombe said Monday [Sept4ember 16, 2024] the project lacks provincial support.

…

Lacombe pointed to Premier François Legault indicating in 2022 that no mining project will be carried out without what’s referred to in the province as “social acceptability” — essentially, buy-in from affected communities.

Natural Resources Minister Blanchette Vézina said the company’s request for funding from Investissement Québec wouldn’t be successful because it lacks public support.

Lomiko Metals has not responded to requests from Radio-Canada for an interview. It’s not clear what the company will do next, or what will happen with a referendum on the project scheduled for November 2025.

…

Embedded in the September 17, 2024 news item is a radio segment where an expert further dissects the implications of the news.

For anyone interested in graphite, I have a January 3, 2023 posting, “Making graphite from coal and a few graphite facts.” There have been some changes with the ‘graphite facts’ since the posting was published but most of the other information should still be valid.

Here are the updated facts from the Natural Resources Canada Graphite Facts webpage, which was updated March 1, 2024,

Graphite is a non-metallic mineral that has properties similar to metals, such as a good ability to conduct heat and electricity. Graphite occurs naturally or can be produced synthetically. Purified natural graphite has higher crystalline structure and offers better electrical and thermal conductivity than synthetic material.

Key facts

  • In 2022, global graphite mine production was about 1.3 million tonnes, a 15% increase from 2021.
  • Canadian natural graphite production comes from the Lac des Iles mine in Quebec.
  • Canada ranks as the sixth global producer of graphite with 13,000 tonnes of production in 2022.
  • Canada exported $22 million worth of natural graphite and $14 million worth of synthetic graphite globally in 2022, mostly to the United States.

…

Production

The Lac des Iles mine in Quebec is the only mine in Canada that produced graphite in 2022 [emphasis mine]. However, many other companies are working on advancing graphite projects. Canada produced 13,000 tonnes of natural graphite in 2022, which was an increase from 2021 of 9,743 tonnes.

…

International context

Global production and demand for graphite are anticipated to increase in the coming years, largely because of the use of graphite in the batteries of electric vehicles. In 2022, global consumption of graphite reached 3.8 million tonnes, compared to 3.6 million tonnes in 2021. Synthetic graphite accounted for about 56% of the graphite consumption, which was concentrated largely in Asia. North America consumes only 1% of global natural graphite, but almost 9% of synthetic graphite.

…

Global mine production of graphite was 1.3 million tonnes in 2022, up 15% compared to the previous year. China is the leading global producer, accounting for 66% of production in 2022. Canada ranks sixth globally for natural graphite production, producing about 1% of global natural graphite.

…

It seems Lomiko Metals’ La Loutre mine will not be adding to the country’s graphite production. I wonder what the company will do now as that La Loutre mine appears to be its chief asset, from a November 23, 2023 news release, Note: A link has been removed,

Montreal, Quebec – November 23, 2023 – Lomiko Metals Inc. (TSX.V: LMR) (“Lomiko Metals” or the “Company”) is pleased to announce the launch of a private placement (the “Private Placement“) to support the Company’s progress with its graphite and lithium projects in Quebec, Canada. The Private Placement will consist of hard dollar units for gross proceeds of up to $500,000.

Belinda Labatte, CEO and Director of Lomiko Metals: “Lomiko has accomplished many milestones in the last 18 months, including an updated Mineral Resource Estimate for La Loutre, environmental baseline studies and advancing the metallurgical studies. With this financing and committed investors, we will advance pre-feasibility level initiatives, and continue to advance the important discussions with communities, partners and First Nation Kitigan Zibi.”

…

Retirement of Director

A special thank you and note of appreciation for Paul Gill, Executive Chair, who will not stand for re-election as he pursues other opportunities. We appreciate his service to the company and long-standing leadership at Lomiko. We wish him well in his future endeavours. Paul Gill will continue to serve as Executive Chair until the Company’s Annual and Special Meeting on December 20, 2023.

About Lomiko Metals Inc.

The Company holds mineral interests in its La Loutre graphite development in southern Quebec. The La Loutre project site is within the Kitigan Zibi Anishinabeg (KZA) First Nation’s territory. The KZA First Nation is part of the Algonquin Nation, and the KZA traditional territory is situated within the Outaouais and Laurentides regions.​ Located 180 kilometers northwest of Montreal, the property consists of one large, continuous block with 76 mineral claims totaling 4,528 hectares (45.3 km2).

…

In addition to La Loutre, Lomiko is working with Critical Elements Lithium Corporation towards earning its 49% stake in the Bourier Project as per the option agreement announced on April 27th, 2021. The Bourier project site is located near Nemaska Lithium and Critical Elements south-east of the Eeyou Istchee James Bay territory in Quebec which consists of 203 claims, for a total ground position of 10,252.20 hectares (102.52 km2), in Canada’s lithium triangle near the James Bay region of Quebec that has historically housed lithium deposits and mineralization trends.

This is quite a setback for Lomiko Metals.

October 2024

It seems that while the company has regrouped it has entirely given up on La Loutre, from an October 30, 2024 news release,

October 30th, 2024 – Montreal, Québec: Lomiko Metals Inc. (TSX.V: LMR) (“Lomiko Metals” or the “Company”) is pleased to announce that the 2024 Beep-Map prospecting and sampling program is well underway on the Grenville Graphite Mineral Belt regional graphite exploration project.  The “Grenville” project includes 268 mineral claims covering 15,639 hectares on six blocks in the Laurentian region of Quebec, approximately 200 kilometers northwest of Montréal within a 100 km radius of the Company’s flagship La Loutre graphite project [emphasis mine].  The 2024 work is focused on following up on the very successful graphite results reported in the Company’s press release dated July 11, 2023.  To date, a total of 265 samples have been collected and submitted for analysis from the Dieppe, Meloche, Ruisseau and Tremblant properties, the focus of this campaign. No work is being conducted on the Carmin or North Low properties at this time.  The results of the exploration campaign will be reported as they become available.  The regional exploration program focuses on improving knowledge of graphite showings at the most prospective targets outlined in the 2022 and 2023 exploration programs.

Corporate and market update

Lomiko is part of the global transition to electrification and localization of transportation supply chains, a change that impacts all forms of transportation, cars, heavy equipment, marine etc. It also impacts communities and our talent pool to build these businesses of the future. Natural flake graphite, and specifically fine flake graphite, is crucial for the development of the North American anode industry in the new energy framework driven by tariffs on critical minerals, long-term supply chain resilience, and responsible domestic industrial growth. The La Loutre graphite is 67% fine flake distribution, making it an important source of long-term future graphite supply [emphasis mine] with demonstrated success for anode battery technology – among other uses currently being evaluated by Lomiko. According to Fortune Business Insights report dated October 14, 2024, the North American EV market is expected to grow almost quadruple to $230 billion in 2030 from $63 billion in 2022, with growth from other transportation sectors still nascent. Lomiko continues to engage with partners, customers and suppliers in building the future of this industry and developing R&D for the responsible extraction of this material.

Lomiko is initiating the reimbursement process for its recently awarded grant from the United States government and contribution agreement from the Canadian government, for work completed to date and within the scope of the agreements. It is the recipient of a Department of Defense (“DoD”) Technology Investment Agreement (“TIA”) grant of US$8.35 million (approximately CA$11.4 million) where Lomiko will match the funding over a period of 5 years, for a total agreement with the DoD of US$16.7 million. The grant falls under Title III of the Defense Production Act and is funded through the Inflation Reduction Act to ensure energy security in North America. The Company has also been approved for funding of CA$4.9 million in a non-repayable contribution agreement from the Critical Mineral Research, Development and Demonstration (CMRDD) program administered by Natural Resources Canada, with the total project cost being CA$6.6 million. The announcement was made on May 16, 2024 and can be viewed on our website at www.lomiko.com.

In addition, Lomiko announces the resignation of CFO and Corporate Secretary, Vince Osbourne, who will be pursuing a role with a private company and maintain a strategic advisory role with Lomiko going forward. Jacqueline Michael, Controller, will replace Vince Osbourne as CFO on an interim basis, with the role of Corporate Secretary to be assumed by current professionals working with Lomiko.

On behalf of the board of directors and management, Belinda Labatte, CEO and Interim Chair of the board of directors stated: “Vince has been an integral member of the Lomiko team, and we wish him success in his future endeavors, and we are pleased to continue our working relationship in his new capacity to Lomiko as advisor to the Company.”

…

Now with a new administration entering the US White House has a chief advisor and co-leader of a new government agency [Department of Government Efficiency] in Elon Musk who is extremely wealthy and has many businesses, notably Tesla, an electronic vehicle (EV) business. It would seem that M. Musk might have an interest in easy access to minerals important to Tesla’s business.

I wonder how this is going to work out.

New principles for AI (artificial intelligence) research along with some history and a plea for a democratic discussion

Leave a reply

For almost a month I’ve been meaning to get to this Feb. 1, 2017 essay by Andrew Maynard (director of Risk Innovation Lab at Arizona State University) and Jack Stilgoe (science policy lecturer at University College London [UCL]) on the topic of artificial intelligence and principles (Note: Links have been removed). First, a walk down memory lane,

Today [Feb. 1, 2017] in Washington DC, leading US and UK scientists are meeting to share dispatches from the frontiers of machine learning – an area of research that is creating new breakthroughs in artificial intelligence (AI). Their meeting follows the publication of a set of principles for beneficial AI that emerged from a conference earlier this year at a place with an important history.

In February 1975, 140 people – mostly scientists, with a few assorted lawyers, journalists and others – gathered at a conference centre on the California coast. A magazine article from the time by Michael Rogers, one of the few journalists allowed in, reported that most of the four days’ discussion was about the scientific possibilities of genetic modification. Two years earlier, scientists had begun using recombinant DNA to genetically modify viruses. The Promethean nature of this new tool prompted scientists to impose a moratorium on such experiments until they had worked out the risks. By the time of the Asilomar conference, the pent-up excitement was ready to burst. It was only towards the end of the conference when a lawyer stood up to raise the possibility of a multimillion-dollar lawsuit that the scientists focussed on the task at hand – creating a set of principles to govern their experiments.

The 1975 Asilomar meeting is still held up as a beacon of scientific responsibility. However, the story told by Rogers, and subsequently by historians, is of scientists motivated by a desire to head-off top down regulation with a promise of self-governance. Geneticist Stanley Cohen said at the time, ‘If the collected wisdom of this group doesn’t result in recommendations, the recommendations may come from other groups less well qualified’. The mayor of Cambridge, Massachusetts was a prominent critic of the biotechnology experiments then taking place in his city. He said, ‘I don’t think these scientists are thinking about mankind at all. I think that they’re getting the thrills and the excitement and the passion to dig in and keep digging to see what the hell they can do’.

The concern in 1975 was with safety and containment in research, not with the futures that biotechnology might bring about. A year after Asilomar, Cohen’s colleague Herbert Boyer founded Genentech, one of the first biotechnology companies. Corporate interests barely figured in the conversations of the mainly university scientists.

Fast-forward 42 years and it is clear that machine learning, natural language processing and other technologies that come under the AI umbrella are becoming big business. The cast list of the 2017 Asilomar meeting included corporate wunderkinds from Google, Facebook and Tesla as well as researchers, philosophers, and other academics. The group was more intellectually diverse than their 1975 equivalents, but there were some notable absences – no public and their concerns, no journalists, and few experts in the responsible development of new technologies.

Maynard and Stilgoe offer a critique of the latest principles,

The principles that came out of the meeting are, at least at first glance, a comforting affirmation that AI should be ‘for the people’, and not to be developed in ways that could cause harm. They promote the idea of beneficial and secure AI, development for the common good, and the importance of upholding human values and shared prosperity.

This is good stuff. But it’s all rather Motherhood and Apple Pie: comforting and hard to argue against, but lacking substance. The principles are short on accountability, and there are notable absences, including the need to engage with a broader set of stakeholders and the public. At the early stages of developing new technologies, public concerns are often seen as an inconvenience. In a world in which populism appears to be trampling expertise into the dirt, it is easy to understand why scientists may be defensive.

I encourage you to read this thoughtful essay in its entirety although I do have one nit to pick:  Why only US and UK scientists? I imagine the answer may lie in funding and logistics issues but I find it surprising that the critique makes no mention of the international community as a nod to inclusion.

For anyone interested in the Asolimar AI principles (2017), you can find them here. You can also find videos of the two-day workshop (Jan. 31 – Feb. 1, 2017 workshop titled The Frontiers of Machine Learning (a Raymond and Beverly Sackler USA-UK Scientific Forum [US National Academy of Sciences]) here (videos for each session are available on Youtube).

Soft contact lenses key to supercapacitor breaththrough

Leave a reply

It seems like pretty exciting news for anyone following the supercapacitor story but they are being awfully cagey about it all in a Dec. 6, 2016 news item on Nanowerk,

Ground-breaking research from the University of Surrey and Augmented Optics Ltd., in collaboration with the University of Bristol, has developed potentially transformational technology which could revolutionise the capabilities of appliances that have previously relied on battery power to work.

This development by Augmented Optics Ltd., could translate into very high energy density super-capacitors making it possible to recharge your mobile phone, laptop or other mobile devices in just a few seconds.

The technology could have a seismic impact across a number of industries, including transport, aerospace, energy generation, and household applications such as mobile phones, flat screen electronic devices, and biosensors. It could also revolutionise electric cars, allowing the possibility for them to recharge as quickly as it takes for a regular non-electric car to refuel with petrol – a process that currently takes approximately 6-8 hours to recharge. Imagine, instead of an electric car being limited to a drive from London to Brighton, the new technology could allow the electric car to travel from London to Edinburgh without the need to recharge, but when it did recharge for this operation to take just a few minutes to perform.

I imagine the reason for the caginess has to do with the efforts to commercialize the technology. In any event, here’s a little more from a Dec. 5, 2016 University of Surrey press release by Ashley Lovell,

Supercapacitor buses are already being used in China, but they have a very limited range whereas this technology could allow them to travel a lot further between recharges. Instead of recharging every 2-3 stops this technology could mean they only need to recharge every 20-30 stops and that will only take a few seconds.

Elon Musk, of Tesla and SpaceX, has previously stated his belief that supercapacitors are likely to be the technology for future electric air transportation. We believe that the present scientific advance could make that vision a reality.

The technology was adapted from the principles used to make soft contact lenses, which Dr Donald Highgate (of Augmented Optics, and an alumnus of the University of Surrey) developed following his postgraduate studies at Surrey 40 years ago. Supercapacitors, an alternative power source to batteries, store energy using electrodes and electrolytes and both charge and deliver energy quickly, unlike conventional batteries which do so in a much slower, more sustained way. Supercapacitors have the ability to charge and discharge rapidly over very large numbers of cycles. However, because of their poor energy density per kilogramme (approximately just one twentieth of existing battery technology), they have, until now, been unable to compete with conventional battery energy storage in many applications.

Dr Brendan Howlin of the University of Surrey, explained: “There is a global search for new energy storage technology and this new ultra capacity supercapacitor has the potential to open the door to unimaginably exciting developments.”

The ground-breaking research programme was conducted by researchers at the University of Surrey’s Department of Chemistry where the project was initiated by Dr Donald Highgate of Augmented Optics Ltd. The research team was co-led by the Principal Investigators Dr Ian Hamerton and Dr Brendan Howlin. Dr Hamerton continues to collaborate on the project in his new post at the University of Bristol, where the electrochemical testing to trial the research findings was carried out by fellow University of Bristol academic – David Fermin, Professor of Electrochemistry in the School of Chemistry.

Dr Ian Hamerton, Reader in Polymers and Composite Materials from the Department of Aerospace Engineering, University of Bristol said: “While this research has potentially opened the route to very high density supercapacitors, these *polymers have many other possible uses in which tough, flexible conducting materials are desirable, including bioelectronics, sensors, wearable electronics, and advanced optics. We believe that this is an extremely exciting and potentially game changing development.”

*the materials are based on large organic molecules composed of many repeated sub-units and bonded together to form a 3-dimensional network.

Jim Heathcote, Chief Executive of both Augmented Optics Ltd and Supercapacitor Materials Ltd, said: “It is a privilege to work with the teams from the University of Surrey and the University of Bristol. The test results from the new polymers suggest that extremely high energy density supercapacitors could be constructed in the very new future. We are now actively seeking commercial partners [emphasis mine] in order to supply our polymers and offer assistance to build these ultra high energy density storage devices.”

I was not able to find a website for Augmented Optics but there is one for SuperCapacitor Materials here.

Cardiac pacemakers: Korea’s in vivo demonstration of a self-powered one* and UK’s breath-based approach

Leave a reply

As i best I can determine ,the last mention of a self-powered pacemaker and the like on this blog was in a Nov. 5, 2012 posting (Developing self-powered batteries for pacemakers). This latest news from The Korea Advanced Institute of Science and Technology (KAIST) is, I believe, the first time that such a device has been successfully tested in vivo. From a June 23, 2014 news item on ScienceDaily,

As the number of pacemakers implanted each year reaches into the millions worldwide, improving the lifespan of pacemaker batteries has been of great concern for developers and manufacturers. Currently, pacemaker batteries last seven years on average, requiring frequent replacements, which may pose patients to a potential risk involved in medical procedures.

A research team from the Korea Advanced Institute of Science and Technology (KAIST), headed by Professor Keon Jae Lee of the Department of Materials Science and Engineering at KAIST and Professor Boyoung Joung, M.D. of the Division of Cardiology at Severance Hospital of Yonsei University, has developed a self-powered artificial cardiac pacemaker that is operated semi-permanently by a flexible piezoelectric nanogenerator.

A June 23, 2014 KAIST news release on EurekAlert, which originated the news item, provides more details,

The artificial cardiac pacemaker is widely acknowledged as medical equipment that is integrated into the human body to regulate the heartbeats through electrical stimulation to contract the cardiac muscles of people who suffer from arrhythmia. However, repeated surgeries to replace pacemaker batteries have exposed elderly patients to health risks such as infections or severe bleeding during operations.

The team’s newly designed flexible piezoelectric nanogenerator directly stimulated a living rat’s heart using electrical energy converted from the small body movements of the rat. This technology could facilitate the use of self-powered flexible energy harvesters, not only prolonging the lifetime of cardiac pacemakers but also realizing real-time heart monitoring.

The research team fabricated high-performance flexible nanogenerators utilizing a bulk single-crystal PMN-PT thin film (iBULe Photonics). The harvested energy reached up to 8.2 V and 0.22 mA by bending and pushing motions, which were high enough values to directly stimulate the rat’s heart.

Professor Keon Jae Lee said:

“For clinical purposes, the current achievement will benefit the development of self-powered cardiac pacemakers as well as prevent heart attacks via the real-time diagnosis of heart arrhythmia. In addition, the flexible piezoelectric nanogenerator could also be utilized as an electrical source for various implantable medical devices.”

This paper is behind a paywall.

There was a May 15, 2014 KAIST news release on EurekAlert announcing this same piece of research but from a technical perspective,

The energy efficiency of KAIST’s piezoelectric nanogenerator has increased by almost 40 times, one step closer toward the commercialization of flexible energy harvesters that can supply power infinitely to wearable, implantable electronic devices

NANOGENERATORS are innovative self-powered energy harvesters that convert kinetic energy created from vibrational and mechanical sources into electrical power, removing the need of external circuits or batteries for electronic devices. This innovation is vital in realizing sustainable energy generation in isolated, inaccessible, or indoor environments and even in the human body.

Nanogenerators, a flexible and lightweight energy harvester on a plastic substrate, can scavenge energy from the extremely tiny movements of natural resources and human body such as wind, water flow, heartbeats, and diaphragm and respiration activities to generate electrical signals. The generators are not only self-powered, flexible devices but also can provide permanent power sources to implantable biomedical devices, including cardiac pacemakers and deep brain stimulators.

However, poor energy efficiency and a complex fabrication process have posed challenges to the commercialization of nanogenerators. Keon Jae Lee, Associate Professor of Materials Science and Engineering at KAIST, and his colleagues have recently proposed a solution by developing a robust technique to transfer a high-quality piezoelectric thin film from bulk sapphire substrates to plastic substrates using laser lift-off (LLO).

Applying the inorganic-based laser lift-off (LLO) process, the research team produced a large-area PZT thin film nanogenerators on flexible substrates (2 cm x 2 cm).

“We were able to convert a high-output performance of ~250 V from the slight mechanical deformation of a single thin plastic substrate. Such output power is just enough to turn on 100 LED lights,” Keon Jae Lee explained.

The self-powered nanogenerators can also work with finger and foot motions. For example, under the irregular and slight bending motions of a human finger, the measured current signals had a high electric power of ~8.7 μA. In addition, the piezoelectric nanogenerator has world-record power conversion efficiency, almost 40 times higher than previously reported similar research results, solving the drawbacks related to the fabrication complexity and low energy efficiency.

Lee further commented,

“Building on this concept, it is highly expected that tiny mechanical motions, including human body movements of muscle contraction and relaxation, can be readily converted into electrical energy and, furthermore, acted as eternal power sources.”

The research team is currently studying a method to build three-dimensional stacking of flexible piezoelectric thin films to enhance output power, as well as conducting a clinical experiment with a flexible nanogenerator.

In addition to the 2012 posting I mentioned earlier, there was also this July 12, 2010 posting which described research on harvesting biomechanical movement ( heart beat, blood flow, muscle stretching, or even irregular vibration) at the Georgia (US) Institute of Technology where the lead researcher observed,

…  Wang [Professor Zhong Lin Wang at Georgia Tech] tells Nanowerk. “However, the applications of the nanogenerators under in vivo and in vitro environments are distinct. Some crucial problems need to be addressed before using these devices in the human body, such as biocompatibility and toxicity.”

Bravo to the KAIST researchers for getting this research to the in vivo testing stage.

Meanwhile at the University of Bristol and at the University of Bath, researchers have received funding for a new approach to cardiac pacemakers, designed them with the breath in mind. From a June 24, 2014 news item on Azonano,

Pacemaker research from the Universities of Bath and Bristol could revolutionise the lives of over 750,000 people who live with heart failure in the UK.

The British Heart Foundation (BHF) is awarding funding to researchers developing a new type of heart pacemaker that modulates its pulses to match breathing rates.

A June 23, 2014 University of Bristol press release, which originated the news item, provides some context,

During 2012-13 in England, more than 40,000 patients had a pacemaker fitted.

Currently, the pulses from pacemakers are set at a constant rate when fitted which doesn’t replicate the natural beating of the human heart.

The normal healthy variation in heart rate during breathing is lost in cardiovascular disease and is an indicator for sleep apnoea, cardiac arrhythmia, hypertension, heart failure and sudden cardiac death.

The device is then briefly described (from the press release),

The novel device being developed by scientists at the Universities of Bath and Bristol uses synthetic neural technology to restore this natural variation of heart rate with lung inflation, and is targeted towards patients with heart failure.

The device works by saving the heart energy, improving its pumping efficiency and enhancing blood flow to the heart muscle itself.  Pre-clinical trials suggest the device gives a 25 per cent increase in the pumping ability, which is expected to extend the life of patients with heart failure.

One aim of the project is to miniaturise the pacemaker device to the size of a postage stamp and to develop an implant that could be used in humans within five years.

Dr Alain Nogaret, Senior Lecturer in Physics at the University of Bath, explained: “This is a multidisciplinary project with strong translational value.  By combining fundamental science and nanotechnology we will be able to deliver a unique treatment for heart failure which is not currently addressed by mainstream cardiac rhythm management devices.”

The research team has already patented the technology and is working with NHS consultants at the Bristol Heart Institute, the University of California at San Diego and the University of Auckland. [emphasis mine]

Professor Julian Paton, from the University of Bristol, added: “We’ve known for almost 80 years that the heart beat is modulated by breathing but we have never fully understood the benefits this brings. The generous new funding from the BHF will allow us to reinstate this natural occurring synchrony between heart rate and breathing and understand how it brings therapy to hearts that are failing.”

Professor Jeremy Pearson, Associate Medical Director at the BHF, said: “This study is a novel and exciting first step towards a new generation of smarter pacemakers. More and more people are living with heart failure so our funding in this area is crucial. The work from this innovative research team could have a real impact on heart failure patients’ lives in the future.”

Given some current events (‘Tesla opens up its patents’, Mike Masnick’s June 12, 2014 posting on Techdirt), I wonder what the situation will be vis à vis patents by the time this device gets to market.
