Portable x-ray machine

It’s all about the adhesive tape according to the researchers at Tribogenics. Yes, they can create x-rays by unrolling scotch tape in a vacuum. Neal Ungerleider’s Dec. 8, 2011 article for Fast Company,

Tribogenics’ products rely on a counterintuitive discovery: X-rays are generated when unrolling Scotch tape in a vacuum. In a Nature article, UCLA researchers Carlos Camara, Juan Escobar, Jonathan Hird, and Seth Putterman detailed how Scotch tape can generate surprisingly large amounts of X-rays thanks to visible radiation generated by static electricity between two contacting surfaces. The research encountered challenges thanks to the fact that Scotch tape and generic brand adhesive tapes generated slightly different energy signatures; the composition of Scotch tape adhesive is a closely guarded 3M trade secret. …

Fox [Dale Fox, Tribogenics’ Chief Scientist] told Fast Company that “every other X-ray source in the world uses a high-voltage transformer connected to a vacuum tube. In contrast, we’ve harnessed the power of the immense voltages in static electricity to create tiny, low-cost, battery-operated X-ray sources for the first time in history. It’s like the jump the electronics industry took when it moved from vacuum tubes to transistors.” According to Fox, Tribogenics has already developed X-ray energy sources the size of a USB memory stick. While Tribogenics representatives declined to discuss pricing for upcoming products, the firm “very comfortably” promised that the cost would be less than 10% than that of any existing X-ray technology.

This technology can be traced back to DARPA (Defense Advanced Research Projects Agency) in 2007 when the agency funded the company’s first research, according to the company website. There have been other military funds as well, the US Army Telemedicine and Advanced Research Center in 2010.

The company describes itself this way (from the home page),

Tribogenics patented technology enables portable, compact x-ray solutions for applications in precious metal, mining, military, medical imaging, security and other industries. By miniaturizing X-ray sources and eliminating the need for high voltage, we can create products and solutions unattainable using existing X-ray technology. Tribogenics revolutionary X-ray solution emerged from DARPA and TATRC-funded initiatives at UCLA and was developed by prominent scientists.

Ungerleider notes that the company has not launched any commercial products yet but this one sure looks interesting,

… ultra-portable X-ray machines show the greatest potential for becoming a disruptive medical technology. Tribogenics’ methods have revolutionary ramifications for catheterized radiation therapy, which currently poses significant radiation risks for patients, doctors, and nurses. According to Fox, the company’s products eliminate the need for radioactive isotopes.

If you are interested in this technology, I would suggest reading Ungerleider’s article for additional details.
