Abstract

ABSTRACT Self-powered technology is a novel power supply technology. In recent years, self-powered intelligent products have attracted much interests. Triboelectric nanogenerators (TENGs) can convert mechanical energy into electrical energy by contact and relative motion, thus providing the possibility of self-powering for electronic equipments. However, TENG-based self-powered technologies are limited by low power output and poor conversion efficiency. In this review, we present the development of TENG-based self-powered systems, with the emphasis on the output power of TENG and how to improve it. Based on the above applications, we propose the idea of TENG-driven self-powered remote robots, providing promising scenarios of small remote robots for land rescue or underwater detection. Due to the limited power output of the current TENGs, there are still some difficulties in driving the robot. Aiming at the problems of low power supply and poor conversion efficiency, we introduce the current attempts to improve the power generation efficiency from the perspectives of mechanical structure, electrode materials and auxiliary tools. We also outline the applications of TENGs as power supply systems in various fields such as sensing, wearable devices, and collecting Marine energy. Finally, we forecast the development prospect of TENG. Graphical abstract

自供电摩擦纳米发电机的研究进展与展望

自供电技术是一种新型的电源技术。近年来，自供电智能产品引起了人们的广泛关注。摩擦电纳米发电机(TENGs)可以通过接触和相对运动将机械能转化为电能，从而为电子设备提供自供电的可能性。然而，基于teng的自供电技术受到低功率输出和低转换效率的限制。在这篇综述中，我们介绍了基于TENG的自供电系统的发展，重点介绍了TENG的输出功率以及如何改进它。基于上述应用，我们提出了teng驱动自供电远程机器人的思路，为小型远程机器人用于陆地救援或水下探测提供了前景广阔的场景。由于目前的teng的输出功率有限，在驱动机器人方面还存在一些困难。针对功率小、转换效率差的问题，从机械结构、电极材料、辅助工具等方面介绍了目前提高发电效率的尝试。我们还概述了TENGs作为电源系统在传感、可穿戴设备和海洋能源收集等各个领域的应用。最后，对TENG的发展前景进行了展望。图形抽象
