In Japan, researchers at Waseda University used a new design process that mimics sandwiches and layers the electronic components in between elastomeric nanosheets to create wearable electronic devices that look like tattoos. In their tests on artificial skin, the tattoo-like devices stayed on for several days. Why would you want an electronic tattoo that sticks to your skin? Other than skipping the needles and pain that come along with real tattoos, these elastomeric nanosheet film tattoos are super easy to print on inkjet printers of circuitry, very comfortable to wear, and can be helpful for medical applications and sports training purposes.
