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.
