ABSTRACT

Recently, researchers have produced a triboelectric nanogenerators (TENGs) technology that can harvest mechanical energy. However, the expensive fabrication materials still hinder its widespread. Thus, we propose a novel cost-effective TENG (N-TENG) by using the napkin to harvest biomechanical energy and sense the human motion. The N-TENG can obtain the short-circuit current (Isc) of 42.38 µA and the open-circuit voltage (Voc) of 363 V, respectively. As for the maximum output power of N-TENG with the size of (5 cm × 5 cm), it can reach 1.52 mW. Furthermore, the N-TENG integrated into the insole can detect the amount of perspiration of the foot to realize the physiological monitoring of the human body. This research not only greatly promoted the TENGs in mechanical energy harvesting but also the development of wearable electronics.

摘要

最近，研究人员开发了一种摩擦纳米发电机 (TENGs) 技术，可以收集机械能。然而，昂贵的制造材料仍然阻碍了它的普及。因此，我们提出了一种新的具有成本效益的 TENG (N-TENG)，通过使用餐巾来收集生物力学能量并感知人体运动。N-TENG 可以分别获得 42.38 µA 的短路电流 (Isc) 和 363 V 的开路电压 (Voc)。尺寸为（5 cm × 5 cm）的N-TENG的最大输出功率可达1.52 mW。此外，集成在鞋垫中的N-TENG可以检测足部的出汗量，实现对人体的生理监测。这项研究不仅极大地促进了TENGs在机械能收集方面的应用，而且也促进了可穿戴电子产品的发展。
