The micromechanical energy caused by a repeating tension is abundant and widely existed in human life, which is usually related to dynamic monitoring in a low‐dimensional system. Here, a 1D tensile triboelectric nanogenerator (TENG) that is consisted of a copper and a latex tube is reported. The subtle TENG can not only serve as a sustainable power source by harvesting tensile mechanical energy, but also operate actively to detect some surrounding mechanical stimulations. Due to the high sensitivity to stretching, the TENG unit shows a self‐powered counting function. Furthermore, a sensor square frame, composed of four TENG units, is demonstrated as a feasible self‐powered electronic fence by effectively monitoring ambient collisions from different directions. In addition, the simulated landslide experiment indicates that the tensile TENG can detect different geological activities and has a directional selectivity that facilitates geological hazard monitoring. This work further expands TENG‐based applications, especially in safety engineering and geological monitoring.

一维摩擦电纳米发电机，通过反复拉伸并作为自供电电子围栏和地质监测器进行操作

由反复张紧引起的微机械能在人类生活中是丰富的，并且广泛存在，这通常与低维系统中的动态监测有关。在此，报道了由铜和乳胶管组成的一维拉伸摩擦电纳米发电机（TENG）。细微的TENG不仅可以通过收集拉伸机械能用作可持续的动力源，而且还可以主动检测周围的一些机械刺激。由于对拉伸的高度敏感性，TENG装置具有自供电计数功能。此外，由四个TENG单元组成的传感器方形框架通过有效地监视来自不同方向的环境碰撞，被证明是可行的自供电电子围栏。此外，模拟滑坡实验表明，张拉滕能探测到不同的地质活动，并具有方向选择性，有利于地质灾害监测。这项工作进一步扩展了基于TENG的应用程序，特别是在安全工程和地质监测方面。
