How Far for the Electronic Skin: From Multifunctional Material to Advanced Applications

Electronic skin that imitates the characteristics and functions of human skin to sense various external signals and records them as different electrical signals has received extensive attention, and much effort has been made on electronic skin for potential medicine application. However, it still needs a long way to achieve practical applications for electronic skin as consumer electronics, the recent progress of electronic skin is reviewed. First, the crucial characteristics in practical electronic skin are analyzed. Subsequently, the technical supports that need to obtain practical electronic skin are also discussed, and electronic skin in terms of short‐term application, medium‐term application and long‐term application are introduced. Finally, suggestions for future development directions in this fascinating field are put forward.
