Development of triboelectric nanogenerators for regeneration of damaged axons

Recently, application of nanogenerator technology for harvesting small-scale biomechanical energy and converting it into electricity, has been introduced as a promising candidate for the regeneration of damaged axons. Among the various types of nanogenerators, triboelectric nanogenerators (TENG) has attracted much attention thanks to their high efficiency, small size and wide choice of materials for triboelectric layers. In this research, TENG composted of two layers of polycaprolactone (PCL)-graphene oxide (GO) and silk fibrous constructs was developed for nerve regeneration. PCL-GO fibrous layer was applied to simultaneously improve mechanicaland interfacial properties as well as entrapment of electrons in the matrix of biodegradable and biocompatible PCL. Moreover, according to the triboelectric series, two nanofibrous layers of PCL-GO and silk had suitable triboelectric potential difference. Our work demonstrated the potential of a TENG as a self-powered system for transient implantable biomedical devices, especially for electrical stimulation and regeneration of neurological damages
