Abstract

Triboelectric nanogenerators (TENGs) are emerging as new technologies to harvest electrical power from mechanical energy. With the distinctive working mechanism of triboelectric nanogenerators, they attract particular interest in healthcare monitoring, wearable electronics, and deformable energy harvesting, which raises the requirement for highly conformable devices with substantial energy outputs. Here, a simple, low-cost strategy for fabricating stretchable triboelectric nanogenerators with ultra-high electrical output is developed. The TENG is prepared using PTFE micron particles (PP-TENG), contributing a different electrostatic induction process compared to TENG based on dielectric films, which was associated with the dynamics of particle motions in PP-TENG. The generator achieved an impressive voltage output of 1000 V with a current of 25 μA over a contact area of 40 × 20 mm². Additionally, the TENG exhibits excellent durability with a stretching strain of 500%, and the electrical output performance does not show any significant degradation even after 3000 cycles at a strain of 400%. The unique design of the device provides high conformability and can be used as a self-powered sensor for human motion detection.

基于聚四氟乙烯（PTFE）颗粒的高性能可拉伸三电纳米发电机

三电纳米发电机（TENGs）正在成为从机械能中获取电能的新技术。三电纳米发电机的工作机理与众不同，因此在医疗保健监测、可穿戴电子设备和可变形能量收集等领域尤其受到关注，这就对具有可观能量输出的高适配性设备提出了更高要求。本文开发了一种简单、低成本的策略，用于制造具有超高电输出的可拉伸三电纳米发电机。拉伸三电纳米发电机使用聚四氟乙烯微米颗粒（PP-TENG）制备，与基于电介质薄膜的拉伸三电纳米发电机相比，其静电感应过程不同，这与 PP-TENG 中颗粒运动的动态有关。在 40 × 20 平方毫米的接触面积上，该发生器的电压输出达到了惊人的 1000 V，电流为 25 μA。此外，该 TENG 在拉伸应变为 500% 的情况下表现出卓越的耐久性，即使在应变为 400% 的情况下循环使用 3000 次，其电气输出性能也没有出现任何明显的下降。该器件设计独特，具有很高的适配性，可用作人体运动检测的自供电传感器。

期刊介绍： Energy & Environmental Materials (EEM) is an international journal published by Zhengzhou University in collaboration with John Wiley & Sons, Inc. The journal aims to publish high quality research related to materials for energy harvesting, conversion, storage, and transport, as well as for creating a cleaner environment. EEM welcomes research work of significant general interest that has a high impact on society-relevant technological advances. The scope of the journal is intentionally broad, recognizing the complexity of issues and challenges related to energy and environmental materials. Therefore, interdisciplinary work across basic science and engineering disciplines is particularly encouraged. The areas covered by the journal include, but are not limited to, materials and composites for photovoltaics and photoelectrochemistry, bioprocessing, batteries, fuel cells, supercapacitors, clean air, and devices with multifunctionality. The readership of the journal includes chemical, physical, biological, materials, and environmental scientists and engineers from academia, industry, and policy-making.
