Harvesting the omnipresent mechanical energy emerges as an essential solution in combating environmental pollution and alleviating energy deficits. However, the ultra-low frequencies and variable amplitudes of most ambient mechanical energy pose significant challenges to effective energy harvesting. To address this issue, this paper reports an innovative triboelectric nanogenerator based on pendulum-rotation transmission mechanism (PR-TENG) designed for efficacious harvesting of continuous low-frequency mechanical energy. It comprises two synergistic units: a transmission unit and a power-generating unit. The transmission unit is capable of converting external low-frequency mechanical excitations into unidirectional rotation. Through an internal speed-increasing mechanism, the rotational speed of the rotor can be further elevated, thereby enabling the power-generating unit to produce a frequency-multiplied output and markedly improving the energy transduction efficiency. The mechanism of triboelectrification employed by the power-generating unit further reduces the total weight of the device, thus advancing its portability. In addition, the coherent coaxial configuration of the device's components significantly enhances compactness and optimizes spatial efficiency. As a practical power source, the PR-TENG is shown to be capable of directly powering LEDs. Owing to its distinctive operational mechanism and structural innovation, the PR-TENG is a promising method to efficiently harvest low-frequency mechanical energy from the ambient environment.

基于摆旋转传输机制的摩擦纳米发电机，用于收集连续低频机械能

收集无处不在的机械能成为对抗环境污染和缓解能源短缺的重要解决方案。然而，大多数环境机械能的超低频和可变幅度对有效的能量收集提出了重大挑战。为了解决这个问题，本文报道了一种基于摆旋转传动机构（PR-TENG）的创新摩擦纳米发电机，旨在有效收集连续低频机械能。它由两个协同单元组成：传输单元和发电单元。传动单元能够将外部低频机械激励转换为单向旋转。通过内部增速机构，可以进一步提高转子的转速，从而使发电机组产生倍频输出，显着提高能量转换效率。发电单元采用的摩擦起电机制进一步减轻了设备的总重量，从而提高了其便携性。此外，该器件组件的相干同轴配置显着增强了紧凑性并优化了空间效率。作为一种实用的电源，PR-TENG 被证明能够直接为 LED 供电。由于其独特的运行机制和结构创新，PR-TENG 是一种从周围环境中有效收集低频机械能的有前景的方法。
