Iontronics is a branch of electronics centered around the utilization of ions, charged atoms or molecules, for electronic processes. Unlike conventional electronics that rely on the movement of electrons through materials, iontronics harnesses the movement of ions to achieve diverse electronic functions via electrical double layers (EDLs). EDLs exhibit significantly higher and more sensitive capacitance, resulting in enhanced output performance. This field extends its influence into research field of energy harvesting, biomedical applications, etc. It explores immense potential to play a pivotal role in realizing a seamless human-machine interface.

The Energy-harvesting (EH) technologies converts mechanical and natural energy into electrical energy. Especially, our main researches focuse on TENG (triboelectric nanogenerators), based on coupling effect of contact electrification and electrostatic induction, and HG (Hydrovoltaic Generator), which converts water movements through specific nanomaterials into electrical energy. EH technologies have a wide range of applications beyond just energy harvesting such as self-powered sensing, power sourcing for actuating, healthcare, and so on. EH make them a promising technology with the potential to revolutionize various industries by providing sustainable and efficient energy solutions for a wide range of applications.
