Triboelectric Nanogenerators: Entirely, Intrinsically, and Autonomously Self‐Healable, Highly Transparent, and Superstretchable Triboelectric Nanogenerator for Personal Power Sources and Self‐Powered Electronic Skins (Adv. Funct. Mater. 40/2019)

Abstract

In article number 1904626, Ying‐Chih Lai, Ho‐Hsiu Chou, and co‐workers develop an entirely, intrinsically, and autonomously self‐healable, highly transparent, and super‐stretchable nanogenerator that can act as not only an energy harvester but also a self‐powered electronic skin. This unprecedented device with energy‐extracting and activity‐sensing abilities is timely and able to advance vast emerging fields including self‐powered electronics, human‐interactive interfaces, and prosthetic and robotic skins.

Self‐Healing Hydrogel Bioelectronics

“…For instance, Lai et al presented an entirely self-healing TENG using healable PDMS and ionic conductive hydrogels as the triboelectric layer and electrode layer, respectively (Figure 20c). [383] The healable PDMS was synthesized based on the coordination interactions between the zinc ions and the condensation polymer of bis(3-aminopropyl)-terminated PDMS and bipyridine groups. The healable hydrogel was crosslinked by borate ester bonds between PVA and tetrahydro borate ions.…”
