An Atlas for Large-Area Electronic Skins

Electronic skins are critical for many applications in human-machine-environment interactions. Tactile sensitivity over large areas can be especially applied to prosthetics. Moreover the potential for wearables interactive surfaces and human robotics have propelled research in this area. In this Element we provide an account and directional atlas of the progress in materials and devices for electronic skins in the context of sensing principles and skin-like features. Additionally we give an overview of essential electronic circuits and systems used in large-area tactile sensor arrays. Finally we present the challenges and provide perspectives on future developments.
