Biomimetic engineering of spider silk fibres with graphene for electric devices with humidity and motion sensitivity

Abstract

A fibrous and electronic spidroin sensor with humidity and human motion sensitivity was engineered by forming graphene sheaths with morphological ripples or overlapped cracks around spidroin fibres. Sensitivity-enhancement design inspired by plant tendrils and the slit organs of spider legs further enabled its application in wearable devices with multi-stimuli responsiveness, high sensitivity, flexibility, biocompatibility and sustainability.
