Electronic Skin for Closed-Loop Systems.

Electronic skin (e-skin) uses advanced electronics and sensor arrays to manufacture human-skin-like robotics skin. The creation of e-skin has been made possible due to various physics effects/mechanisms, innovative materials, structural designs, and advanced fabrication techniques. In this Perspective, we describe the current advances in and emerging uses of e-skin for closed-loop systems, with a view toward applications in smart robotics, Internet of Things, and human-machine interfaces.
