Vodka-powered wireless communications featured Canada’s national anthem

In a joint project between Warwick University (UK) and York University (Canada), researchers sent a text message featuring O Canada (national anthem) in a system that relies on vodka molecules. From the Dec. 18, 2013  news item on Nanowerk,

After successfully text messaging ‘O Canada’ using evaporated vodka, two York University researchers and their UK-based counterpart say their simple system can be used where conventional wireless technology fails.

“Chemical signals can offer a more efficient way of transmitting data inside tunnels, pipelines or deep underground structures. For example, the recent massive clog in London sewer system could have been detected earlier on, and without all the mess workers had to deal with, sending robots equipped with a molecular communication system,” says Professor Andrew Eckford, in whose lab in the Department of Electrical Engineering and Computer Science located in Lassonde School of Engineering, the experiment was conducted.

The Dec. 18, 2013 York University news release (also on EurekAlert), which originated the news item, details how the signaling was achieved (Note: A link has been removed),

The chemical signal, using the alcohol found in vodka in this case, was sent four metres across the lab with the aid of a tabletop fan. It was then demodulated by a receiver which measured the rate of change in concentration of the alcohol molecules, picking up whether the concentration was increasing or decreasing.

“We believe we have sent the world’s first text message to be transmitted entirely with molecular communication, controlling concentration levels of the alcohol molecules, to encode the alphabets with single spray representing bit 1 and no spray representing the bit 0,” says York U doctoral candidate Nariman Farsad, who led the experiment.

Though use of chemical signals is a new method in human communication technology, the biocompatible method is very common in the animal kingdom. Bees for example use chemicals in pheromones when there is a threat to the hive, and so do the Canadian lnyx, when marking territories.

In an article, Tabletop Molecular Communication: Text Messages Through Chemical Signals, in the peer-reviewed journal PLOS ONE, the researchers say their system also fills a major gap in the molecular communication literature, by providing an inexpensive platform for testing theoretical models. This allows researchers to gain real-world experience with molecular communication, cheaply and easily.

“Our system shows that reliable communication is possible and our work motivates future studies on more realistic modelling, analysis, and design of theoretical models and algorithms for molecular communication systems,” says Engineering Professor Weisi Guo at the University of Warwick, who initiated the research during a meeting with Eckford, last year. He adds, “They can also be used to communicate on the nanoscale, for example in medicine where recent advances mean it’s possible to embed sensors into the organs of the body or create miniature robots to carry out a specific task such as targeting drugs to cancer cells.”

York University has also produced a video demonstrating vodka-fueled signaling,

A Dec. 19, 2013 University of Warwick press release provides additional perspective on this achievement (Note: Links have been removed),

Scientists have created a molecular communications system for the transmission of messages and data in challenging environments such as tunnels, pipelines, underwater and within the body.

The technique has a wide range of applications in environments where electromagnetic waves cannot be used, for example in underground structures such as tunnels, pipelines or in underwater environments.

Molecular signalling is a common feature of the plant and animal kingdom – insects for example use pheromones for long-range signalling – but to date continuous data have not been transmitted.

Researchers at the University of Warwick in the UK and the York University in Canada have developed the capability to transform any generic message into binary signals, which in turn is ‘programmed’ into evaporated alcohol molecules to demonstrate the potential of molecular communications. Their results are published in the open access journal PLOS ONE.

Dr Weisi Guo from the School of Engineering at the University of Warwick said: “Imagine sending a detailed message using perfume – it sounds like something from a spy thriller novel, but in reality it is an incredibly simple way to communicate.

“ Of course people have achieved short ranged signalling using chemicals, but we have gone to the next level and successfully communicated continuous and generic messages over several metres.
