제목 Deformable, Visco-poroelastic Ion Pumps for Triboelectric Nanogenerators and Self-Powered Mechanotransducers
초록 Recently, many attempts have been made to implement stretchable triboelectric nanogenerators (TENGs) that can be energy harvesting systems and self-powered electronic devices. Especially, ionic materials such as ionic hydrogels, which are capable of achieving electrical double layers and polarization of ions. We describe a highly deformable and visco-poroelastic ion pump as a potential triboelectric channel with high power density and its impact on self-powered tactile sensors. Upon applying mechanical stimuli such as pressure to the TENG devices, migration and diffusion of the ions that are confined into ionic channel could support the electrode charging derived from contact electrification. This could lead to produce an unprecedented high output power compared to non-ionic and even other ionic systems. In addition, self-powered tactile sensor arrays could be demonstrated for being applicable to interactive touch devices as a promising candidate among electronic skin platforms.
