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.

摩擦纳米发电机驱动的电磁脉冲在精确自供电传感和安全中的应用

物联网（IoT）技术的最新进展加速了微型或纳米系统的实现，这不仅需要开发自供电传感系统，还需要能够保护人身安全的设备。在这里，制造了直接墨水写入（DIW）3D打印的超薄保险丝，并与高性能摩擦电纳米发电机（TENG）耦合。通过以低频滑动动作触发高交流电压TENG，最初具有低电阻的保险丝可以立即从短路状态转换为开路状态。利用这种方法，可以实现各种自供电应用。在这里，我们演示了第一个摩擦电的，完全自供电的系统，该系统可以在不使用计算元件或外部电源的情况下准确地检测包裹掉落。
