Scavenging mechanical vibration energy by combining triboelectric nanogenerators (TENGs) and electromagnetic generators (EMGs) is a renewable and low-carbon way to generate electric power. In this paper, we fabricate a cylindrical structure hybrid nanogenerator based on spring structure to effectively scavenge vibration energy. The introduction of spring structure not only enhances the space utilization, but also supports the moving magnet. Owing to its innovative structure, the instantaneous output power of TENG and EMG are 0.88 mW at a load of 10 MΩ and 216.7 mW at a load of 60 Ω, respectively. With the aids of a power management circuit, the hybrid nanogenerator can provide continuous power for two hygrothermographs connected in series. In addition, a self-powered wireless acceleration sensing monitoring system (SWAM) is developed to measure the acceleration signals of vibration sources. This study provides a novel guideline for harvesting mechanical vibration energy.

通过结合摩擦纳米发电机 (TENG) 和电磁发电机 (EMG) 来清除机械振动能量是一种可再生的低碳发电方式。在本文中，我们制造了一种基于弹簧结构的圆柱形结构混合纳米发电机，以有效清除振动能量。弹簧结构的引入，不仅提升了空间利用率，还支撑了动磁体。由于其创新结构，TENG和EMG的瞬时输出功率在10 MΩ负载下为0.88 mW，在60 Ω负载下为216.7 mW。借助电源管理电路，混合纳米发电机可以为两个串联的温湿度计提供持续电源。此外，开发了一种自供电无线加速度传感监测系统（SWAM）来测量振动源的加速度信号。这项研究为收集机械振动能量提供了新的指导方针。
