报告摘要:

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.
