Skin circuitry means solar-powered interactive LED tattoos
A new process that allows complex circuitry and electrical component to be applied directly to the skin is big news for medical sensors, but it could also lead to LED tattoos, video game interfaces that are integrated into your body,
and even direct control of your muscles by a computer.
It's always been possible to just hot glue electronics to your body, but it's never been a particularly pleasant process for either your skin or the circuits in question. By restructuring circuits to match the elasticity of skin and making them thin enough so that they'll stick with mere molecular forces, researchers have now figured out how to effectively integrate electronic components into your skin without any pain, suffering, or surgery whatsoever.
