The iSkin stickers are sensor-embedded skin stickers that can be used to control mobile devices. These flexible and stretchable stickers were developed by a team from Saarland University in Germany and Carnegie Mellon University in the USA, and are designed to comfortable adhere to human skin.
The stickers are made out of silicone and can be made in a wide variety of shapes and sizes and applied using medical-grade adhesives. The stickers are temporary and can be removed, rolled up and stashed away when not in use.
The iSkin stickers could be used for a range of things including taking and placing phone calls, sending text messages, controlling music playback or carrying out pretty much any other function that you usually associate with a mobile screen.
