Electric Tattoos

Scientists unveiled a new device that attaches to the skin like a temporary tattoo. The epidermal electronic system (EES) based designs are less than 50 microns thick, which means that they are much thinner than a human hair. The electronic components are built on the same polyester back that people may recognize from standard stick-on tattoos.


The technology the team used to create the new devices relies on the EES, which is an ingenious mixture of miniature sensors, light-emitting diodes, tiny transmitters and receivers and networks of carefully crafted wire filaments.
