Abstract: Electronic skin with high sensitivity and fast response time has great application prospects in human body signal monitoring and robotics. By imitating the structure of human skin, this paper proposes a self-locking type of electronic skin, whose upper layer is a regular pyramid array, and the lower layer is irregular undulations. The device has a maximum sensitivity of 190.4kPa-1, a minimum detection pressure of 32Pa, a response time of 8ms, a recovery time of 8 ms, and an excellent stability under 3000 cycles of loading. The device has a simple preparation process and the mold can be recycled to meet the conditions of mass production. The device is applied to distinguishing different mechanical forces and monitoring physiological signals of the human body. It shows good performance and has great development potential.
Key words: electronic skin; sandwich structure; pyramid structure; high sensitivity
