One of the common Sci-Fi troupe is to have a sophisticated computer interface on your body and it might have turned into reality. The Saarland University of Germany announced that their scientist has done exactly that. It’s called Multi-Touch Skin. It will act as same as a phone or tablet screen. The material can be inkjet printed onto a plastic sticker and register a touch from multiple points at once.
The sticker is made of two stacked layers of electrodes that are arranged in a grid. The system will be connected to a Raspberry Pi Zero and the current models material still needs to be programmed to a touch-controller microchip. As of now, a total of four interfaces has been created. The includes a behind-the-ear sticker that controls a music player, a bracelet that can manage an LED lamp, a palm sticker that can let you take a phone call and a forearm sticker that can send text messages. The technology is still in its infancy but it’s not hard to imagine a future where you don’t need hardware devices like headphones and smartwatches to interact with your smart gadgets.
