In this work, an ultra-stretchable and healable hydrogel-based triboelectric nanogenerator (TENG) is prepared for mechanical energy harvesting and self-powered sensing. An ionic conductive hydrogel was developed with graphene oxide and Laponite. as the physical cross-linking points, exhibiting high stretchability (∼1356%) and healable capability. When using the hydrogel as the electrode, the TENG can operate normally at 900% tensile strain, while the electrical output of the TENG can fully recover to the initial value after healing the damage. This hydrogel-based TENG is demonstrated to power wearable electronics, and is used as a self-powered sensor for huRSC advancesUltra-stretchable and healable hydrogel-based triboelectric nanogenerators for energy harvesting and self-powered sensing.PMC903285320170552016YFA0202702Li GXu FChang CPu XLi LZhang PfalseUltra-stretchable and healable hydrogel-based triboelectric nanogenerators for energy harvesting and self-powered sensing.The next-generation multifunctional soft electronic devices require the development of energy devices possessing comparable functions.
