报告摘要:
摩擦纳米发电机(TENG)是一种基于摩擦电和静电感应相结合的新兴技术,可以收集大量未充分利用的低频机械能并将其转化为电能。我们的研究主要集中在用于能量收集和自供电传感的高性能TENG的设计和制造。本讲座将首先介绍基于不同类型电极(包括几何设计的刚性电极、液体电极和3D打印可压缩电极等)的高柔性和可变形TENG的最新成果;接着展示TENG与其他功能设备的组合,例如用于自充电式电动包装的超级电容器,用于大规模能量收集的太阳能电池与电磁发电机,以及用于自供电光电化学水分解系统的光阳极。最后,介绍基于TENG的自供电感测的两个不同概念,包括TENG作为自供电传感器用于主动检测机械搅动引起的动静态过程,以及TENG与传统传感器感应的自供电感测过程中的阻抗匹配效果。
Triboelectric nanogenerator (TENG), a recently emerging technology that is based on the combination of triboelectrication and electrostatic induction, has been found to be a promising solution to harvest large amounts of underutilized and low-frequency mechanical energy and convert them to electricity. Our recent research interest mainly focuses on the design and fabrication of high-performance TENGs for energy harvesting and self-powered sensing. In this presentation, I will firstly introduce a couple of recent achievements regarding highly flexible and deformable TENGs based on different kinds of electrodes, including geometrically designed rigid electrode, liquid electrode and 3D printed compressible electrode,etc. Then, I would like to present the combination of TENGs with other functional devices, such as supercapacitor for self-charging powered package, solar cell or electromagnet generator for large-scale energy harvesting, as well as photoanodes for self-powered photoelectrochemical water splitting system. Lastly, I will illustrate two different concepts of TENG based self-powered sensing, including TENGs as self-powered sensors for actively detecting the static and dynamic processes arising from mechanical agitation, and impedance matching effect between TENGs and traditional sensors induced self-powered sensing process.
