A triboelectric nanogenerator (TENG) is a sustainable solution for the development of smart battery-less devices. It is clean, pollution-free, and cost-effective. Various studies have investigated the fabrication of TENGs using different materials. Biomaterials have great potential in this area. Hair, a natural biomaterial, is made of keratinized proteins having different chains of amino acids. These amino acids act as an active layer for the TENG. In this investigation, animal hair is used to fabricate an active layer of a TENG. This layer is tested with active layers of different biomaterials including egg shell membrane and cellulose from different sources (Bombax ceiba tree cotton, tissue paper cellulose), synthetic materials including Teflon (polytetrafluoroethylene—PTFE) and zinc oxide (ZnO), and metals including copper (Cu) and aluminium (Al). The TENG generated 200 volts peak-to-peak voltage using dog hairs and a PTFE combination. A series combination of 124 light-emitting diodes was also lighted with this TENG. Finally, a smart device was powered using this combination. This work provides a basis for further research using different biomaterials for TENG fabrication.

摩擦电动纳米发电机（TENG）是开发无电池智能设备的可持续解决方案。它清洁，无污染且具有成本效益。各种研究调查了使用不同材料制造的TENG。生物材料在这一领域具有巨大的潜力。头发是一种天然的生物材料，由具有不同氨基酸链的角化蛋白质制成。这些氨基酸充当TENG的活性层。在这项研究中，动物毛被用来制造TENG的活性层。该层经过不同生物材料的活性层测试，包括蛋壳膜和来自不同来源的纤维素（Bombax ceiba树棉，薄页纸纤维素），包括聚四氟乙烯（聚四氟乙烯-PTFE）和氧化锌（ZnO）的合成材料以及包括铜（Cu）和铝（Al）的金属。TENG使用狗毛和PTFE组合产生了200伏的峰峰值电压。该TENG也点亮了124个发光二极管的串联组合。最终，使用此组合为智能设备供电。这项工作为进一步研究使用不同的生物材料制造TENG提供了基础。
