In today's world, people are surrounded by smart wireless devices which require sustainable and eco-friendly power source. Triboelectric nanogenerator (TENG) is emerging as an imperative source to produce clean, cost-effective, and easily fabricated battery-less devices. The emphasis is on using biomaterials to play a vital role for the fabrication of such self- powered system. Herein, an approach is discussed to fabricate a novel TENG from the waste biomaterials (garlic tunic, onion tunic, and almond peel) which successfully harvests the electrical energy from daily human motions (walking and running). Egg shell membrane–polytetrafluoroethylene (ESM–PTFE) TENG generates 56.6 V/0.53 μA and is closely followed by garlic tunic–PTFE TENG with 44.6 V/0.36 μA, onion tunic–PTFE TENG with 41.4 V/0.32 μA, and almond peel–PTFE TENG with 40.2 V/0.29 μA, respectively. Moreover, ESM-based TENG performance is examined using all other biomaterial combinations. These TENGs produce sufficient energy that can power an array of tens of green light-emitting diodes (LEDs). Finally, the power from human activities is harvested to control small portable electronic devices.

使用基于新型生物材料的摩擦纳米发电机从人体运动中清除机械能

在当今世界，人们被需要可持续和环保电源的智能无线设备所包围。摩擦纳米发电机 (TENG) 正在成为生产清洁、经济高效且易于制造的无电池设备的必要来源。重点是使用生物材料在制造这种自供电系统中发挥重要作用。在此，讨论了一种利用废弃生物材料（大蒜外衣、洋葱外衣和杏仁皮）制造新型 TENG 的方法，该材料成功地从人类日常运动（步行和跑步）中获取电能。蛋壳膜-聚四氟乙烯 (ESM-PTFE) TENG 产生 56.6 V/0.53 μA，紧随其后的是大蒜外衣-PTFE TENG 44.6 V/0.36 μA、洋葱外衣-PTFE TENG 41.4 V/0.32 μA 和杏仁皮-具有 40.2 V/0.29 μA 的 PTFE TENG，分别。此外，使用所有其他生物材料组合检查基于 ESM 的 TENG 性能。这些 TENG 产生足够的能量，可为数十个绿色发光二极管 (LED) 的阵列供电。最后，从人类活动中获取能量来控制小型便携式电子设备。
