“Tech Tats” Turn Tattoos Into Body-Monitoring Devices

Chaotic Moon—an Austin-based software design firm—is giving body art more than just aesthetic appeal. Their latest project, called “Tech Tats,” is a set of temporary tattoos made from electromagnetic paint and an ATiny85 micro-controller that can provide real-time health stats—like temperature, sweat conductance, heart rate and hydration level. Though the technology is still in the prototyping phase, Chaotic Moon believes that these tiny, circuit-like tattoos may one day transform the way we bank, visit the doctor or diagnose illnesses at home.
