EcoMat: 便携式自供电传感系统纸基摩擦纳米发电机

背景与成果简介

近年来,作为一种新型的机械能转换技术,基于接触带电和静电感应的耦合效应的摩擦纳米发电机(TENG)在分布式微/纳米电源、高精度传感和便携式高压电源等领域具有很明显的优势。通常,TENG的主要功能组件包括摩擦层和导电层,这两者都需要附着在用作支撑框架的基材上,从而形成可用的器件。根据不同基材的特性,TENG可以实现各种特性以满足不同的实际需求。在众多材料中,纸张(一种日常生活中的常用商品)具有成本低、灵活、轻巧、可集成性和生物相容性等特点,被认为是形成自供电电子设备的超级便携式TENG的有前途的基材或框架材料。然而,粗糙且多孔的结构增加了在连续周期性变形期间破坏直接沉积金属膜而制备的导电层的风险。重庆大学胡陈果教授团队在EcoMat发表了题为“Recent progresses on paper‐based triboelectric nanogenerator for portable self‐powered sensing systems”的综述性文章。本文以纸基摩擦纳米发电机为研究对象,总结了纸基耐久导电层的制备方法。然后,从机械能收集、微纳能源器件、自供电传感器和系统等方面系统地介绍了纸制TENG的最新研究成果。最后,对未来的机遇和挑战进行了预期和讨论。
