'Electronic' Skin Monitors Heart, Brain Function

So-called 'smart' skin is powered by a solar cell

U.S. researchers have developed a stretchy, ultra-thin, self-adhesive material that contains miniature electronics to monitor heart activity, brain waves and muscle movement.  

According to scientists, the new stretchy skin technology, epidermal electronics system (EES), is able to monitor key body functions without the use of cumbersome wires and glues since it attaches to the skin without adhesive.

The material bends, wrinkles and stretches with all the properties of skin. Yet it contains an array of electronic components that can measure everything from heart rate to brain waves.  The so-called “smart” skin is powered by a solar cell.

It was developed by scientists at the University of Illinois, Northwestern University in Illinois, Tufts University in Massachusetts, the Institute of High Performance Computing in Singapore and Dalian University of Technology in China.

John Rogers, professor of materials science and engineering at the University of Illinois Urbana-Champaign, is the project’s lead researcher. He says the electronically-embedded material, which can be placed anywhere on the body, is no thicker than a human hair and is difficult to handle. But they figured out a way around the problem.

“The way that we actually mount these devices on the skin uses ideas borrowed directly from kids’ temporary transfer tattoos," says Rogers, "which is that the device is so floppy, and flexible and skin-like that you can’t mechanically manipulate them effectively. You grab them on one edge and they kind of collapse and crumple under their own weight.”

So the researchers mounted the “smart” skins onto thin, water soluble polymer backings.  After the epidermal electronics device is applied face down onto real skin, the backing is rinsed away.

Rogers says researchers even used temporary tattoos as the backing.

"Temporary tattoos are already low cost, the materials have been worked out, the adhesion is good, why not just use that materials technology as a substrate. And oh, by the way, it provides a way to conceal the electronics to the extent that might be interesting for certain applications.”

Depending on where the “smart” skin is applied, Rogers says it’s possible to monitor the heart’s electrical activity, the contraction of muscles in the arm or the electrical activity of the brain.

“It also turns out that that data can be used as a type of human-machine interface for controlling computer systems, for example. And we demonstrated that concept using electrical activity measured on the throat as the wearer was speaking different words to control a cursor in a simple computer game.”

Researchers say the technology could be helpful to people with neuro-muscular diseases like Lou Gehrig’s disease.

When the German Nazi army occupied the Polish city of Lodz in 1939, it marked the beginning of a long nightmare for the Jewish community that once made up one third of the population. Roughly 200,000 people were forced into the Lodz Ghetto. Less than 7,000 survived. As VOA’s Kane Farabaugh reports, some survivors gathered at the Union League Club in Chicago on the 70th anniversary of the liquidation of the Lodz Ghetto to remember those who suffered at the hands of the Nazi regime.

Video Aging Will Reduce Economic Growth Worldwide in Coming Decades

The world is getting older, fast. And as more people retire each year, fewer working-age people will be there to replace them. Bond rating agency Moody’s says that will lead to a decline in household savings; reducing global investments - which in turn, will lead to slower economic growth around the world. But experts say it’s not too late to mitigate the economic impact of the world’s aging populations. Mil Arcega has more.
