Biowaste-based nontoxic and flexible triboelectric nanogenerators (TENGs) with high performance are greatly recommended for eco-friendly low-cost mechanical energy harvesting. In this paper, a peanut shell powder (PSP)-based TENG is proposed with high output performance by utilizing peanut outer shells, which is a green and economical biowaste material produced over six million tons per year worldwide. The PSP-TENG generated a high open circuit voltage, short circuit current, and instantaneous power of 910 V, 104.5 μA, and 12 mW, respectively, by hand excitation force. Similarly, the fabricated device generated an open circuit voltage, short circuit current, and instantaneous power of 390 V, 14 μA, and 1.3 mW, respectively, under uniform applied force with 10 Hz frequency. For real-time zero energy consuming applications, the proposed PSP-TENG showed exemplary energy scavenging performance from human body motions. Furthermore, it is capable of easily powering up 150 commercial light-emitting diodes and an electronic calculator. Hence, the excellent performance from the fabricated biowaste-based PSP-TENG revealed its promising role for environmental-friendly and economical self-powered devices.

用于生物力学能量清除和可持续供电的生物废物花生壳粉基摩擦纳米发电机

强烈建议将高性能的基于生物废物的无毒挠性摩擦电纳米发电机（TENG）应用于环保的低成本机械能收集。本文提出了一种利用花生壳粉（PSP）的TENG，该花生利用花生壳是一种高产量的产品，而花生壳是一种绿色且经济的生物废料，全球每年生产超过600万吨。PSP-TENG通过手动激励力分别产生了910 V，104.5μA和12 mW的高开路电压，短路电流和瞬时功率。类似地，在以10 Hz的频率均匀施加力的情况下，所制造的器件分别产生390 V，14μA和1.3 mW的开路电压，短路电流和瞬时功率。对于实时零能耗应用，拟议的PSP-TENG显示了人体运动产生的示例性能量清除性能。此外，它能够轻松地为150个商用发光二极管和一个电子计算器供电。因此，基于生物废料的PSP-TENG的出色性能表明了其在环保，经济的自供电设备方面的有希望的作用。
