Electromagnetic Pulse Powered by a Triboelectric Nanogenerator with Applications in Accurate Self‐Powered Sensing and Security

Recent advances in the Internet of Things (IoTs) technology have accelerated the realization of micro or nano systems that necessitate not only the development of a self‐powered sensing system, but also devices that are able to protect personal security. Here, a direct ink write (DIW) 3D‐printed ultrathin fuse is fabricated and coupled with a high performance triboelectric nanogenerator (TENG). By triggering the high‐AC voltage TENG with a low‐frequency sliding motion, the fuse, which initially has low resistance, can instantly transition from a short‐circuit state to an open circuit state. Utilizing this method, a variety of self‐powered applications can be realized. Here, the first triboelectric, fully self‐powered system is demonstrated, which can accurately detect package drops without the use of a computing element or an external power source. In addition, by coupling the TENG, 3D printed fuse, and logic circuit elements, a self‐powered security device is developed, in which users are able to quickly change sensitive information if it is at risk of exposure by a single sliding motion on the TENG.
