I have been recently reading a lot about epidermal electronics. Pretty soon patients in hospitals (and sports people) should be able to wear skin mounted electrodes to be able to measure a variety of physiological indicators in real time for a prolonged period of time.
The latest innovation comes from the University of Illinois. A new device looking like a tattoo, has been developed and proposed as an innovative smart skin solution. Researchers at the University of Illinois who came up with this device made circuits with a wide array of components, to prove it could work: sensors, LEDs, transistors, radio frequency capacitors and wireless antennas. The devices can draw power from induction or even from mini solar cells!
Inventors say they could be used for various medical applications, especially sensors that monitor heart and muscle activity, which currently require conductive gels and/or relatively bulky equipment. To prove it, they measured electrical activity produced by the heart, brain, and skeletal muscles, some data are reported in Science.
This is impressive technology, pushing the boundaries of wearable sensors and providing incredible possibilities for studying human movement.
