A team of engineers today announced a discovery that could change the world of electronics forever. Called an “epidermal electronic system” (EES), it’s basically an electronic circuit mounted on your skin, designed to stretch, flex, and twist — and to take input from the movements of your body.
EES is a leap forward for wearable technologies, and has potential applications ranging from medical diagnostics to video game control and accelerated wound-healing. Engineers John Rogers and Todd Coleman, who worked on the discovery, tell io9 it’s a huge step towards erasing the divide that separates machine and human.
Coleman and Rogers say they developed EES to forego the hard and rigid electronic “wafer” format of traditional electronics in favor of a softer, more dynamic platform.
To accomplish this, their team brought together scientists from several labs to develop “filamentary serpentine” (threadlike and squiggly) circuitry. When this circuitry is mounted on a thin, rubber substrate with elastic properties similar to skin, the result is a flexible patch that can bend and twist, or expand and contract, all without affecting electronic performance. This video demonstrates the resilience of the EES patch, and how easily it can be applied. The patch (comprised of the circuitry and rubber substrate) is first mounted on a thin sheet of water-soluble plastic, then applied to the skin with water like a temporary tattoo.
