you may have an electronic tattoo: what will it serve?

A butterfly on the shoulder, a pirate on the forearm ... So far, nothing very original for a tattoo. Except that the Chinese researcher Nanshu Lu, had the idea of ​​incorporating an electronic circuit there. She has received the grand prize Netexplo forum, dedicated to digital innovations, for this invention.
In practice, an electronic tattoo sticks to the body. It contains the transistors, diodes and miniaturized sensors.
What's the point?
"The potential applications are limited only by our imagination," said the young researcher who developed these tattoos at the University of Texas at Austin.
More specifically, the first application should be medical. These electronic tattoos are able to measure the activity of the heart, brain and muscles. They may for example allow doctors to follow, remote cardiac patients, without the need for electrodes and son traditionally used to collect biological data. The data transmission is wireless, with built in tattoo issuers.
But in the medium term, these electronic tattoos could be used for video games (man-machine interfaces) or sports (measurement of heart rate during exercise, or other parameters).
