Ultra-stable and self-healing coordinated collagen-based multifunctional double-network organohydrogel e-skin for multimodal sensing monitoring of strain-resistance, bioelectrode, and self-powered triboelectric nanogenerator

A new type of collagen-based composite conductive organohydrogel sensor was rationally designed and prepared, which realized simultaneous growth of mechanical property and self-healing function in terms of structure, possessed excellent environmental stability and multifunctionality in terms of performance, and achieved the multimodal monitoring through multi-channel data acquisition including strain-resistance sensing, bioelectric sensing and TENG self-powered sensing in terms of application.
