The Skin-On interface, developed by researchers at the University of Bristol in partnership with Telecomm ParisTech and Sorbonne University, mimics human skin in appearance but also in sensing resolution.

The researchers adopted a bio-driven approach to developing a multi-layer, silicone membrane that mimics the layers present in human skin. This is made up of a surface textured layer, an electrode layer of conductive threads and a hypodermis layer. Not only is the interface more natural than a rigid casing, it can also detect a plethora of gestures made by the end-users. As a result, the artificial skin allows devices to 'feel' the user's grasp -- its pressure and location, and can detect interactions such as tickling, caressing, even twisting and pinching.
