The team was led by John Rogers of the University of Illinois—he has been working on ultra-thin electronic skin patches for several years. Just two years ago, he and his team developed a skin patch that sported sensors, radio frequency capacitors, LEDs, transistors, wireless antennas, conductive coils and even solar cells for power. Other researchers have also been hard at work developing patches for applying directly to the skin, or in one case, a tooth. In this latest effort the researchers have fine tuned a patch that resembles a tattoo once applied—it’s meant for one specific task—monitoring skin temperature.
