Abstract

Tactile sensing is of great importance in developing human-machine interface, remote control, and security systems. Here, a self-triggered alarm system based on the one-piece triboelectric nanosensor (TENS) is reported. By using nitrocellulose (NC) membrane as the triboelectric material, the as-designed TENS can not only sensitively respond to physical contacts in a self-triggered mode but also securely detect the third-level details of latent fingerprint. The self-triggered idea based on the triboelectric nanogenerator is compatible with intelligent interactive interface. Besides, this TENS can be conveniently fabricated and integrated into arrays at a large scale due to its freestanding, simple, and low-cost characteristics. This work presents alternative perspectives for the practical applications of the multifunctionalized TENS.
