Triboelectric nanogenerators (TENGs) are being widely studied as a new way to harvest environmental energy. TENGs can reliably provide energy for low-power sensors, which are widely used in industry and modern life. Aiming to convert external random vibration energy into controllable electrical energy, this paper presented a travel switch integrated mechanical regulation triboelectric nanogenerator (TSMR–TENG) with linear–rotational motion transformation mechanism. The TSMR–TENG consisted of a shell, linear–rotational motion transformation mechanism, inertia wheel, and travel switch. This structure possessed the advantages of small size, easy integration, and high reliability. In the device, the linear–rotational motion transformation mechanism converted linear random vibrations into rotation, and then the energy of rotation was stored in a spiral spring. When enough energy accumulated, the travel switch turned on, and then the spiral spring caused the inertia wheel to rotate. The triboelectric materials on the inertia wheel slid against a copper electrode, which converted the stored energy into electricity. The TSMR–TENG achieved controllable electrical energy output under random vibration excitation. The open–circuit voltage of the TSMR–TENG was about 400 V and its short-circuit current was 17 $\mathrm{\mu }$A. The TSMR–TENG lit up 500 light-emitting diodes in a single operation and drove commercial thermometers through rectifier bridges and capacitors. This work provides a new type of TENG that can generate electricity steadily in the natural environment.

摩擦电纳米发电机（TENGs）被广泛研究为一种收集环境能量的新方法。TENG可以可靠地为低功率传感器提供能量，该传感器已在工业和现代生活中广泛使用。为了将外部随机振动能量转换为可控制的电能，本文提出了一种具有线性-旋转运动转换机制的行程开关集成机械调节摩擦电纳米发电机（TSMR-TENG）。TSMR-TENG由壳体，线性-旋转运动转换机构，惯性轮和行程开关组成。该结构具有体积小，易于集成和可靠性高的优点。在设备中，线性-旋转运动转换机制将线性随机振动转换为旋转，然后将旋转能量存储在螺旋弹簧中。当积累了足够的能量时，行程开关打开，然后螺旋弹簧使惯性轮旋转。惯性轮上的摩擦电材料在铜电极上滑动，从而将存储的能量转换为电能。TSMR–TENG在随机振动激励下实现了可控的电能输出。TSMR–TENG的开路电压约为400 V，其短路电流为17 TSMR–TENG在随机振动激励下实现了可控的电能输出。TSMR–TENG的开路电压约为400 V，其短路电流为17 TSMR–TENG在随机振动激励下实现了可控的电能输出。TSMR–TENG的开路电压约为400 V，其短路电流为17$\mathrm{\mu }$A.
