Self-powered nanotechnology based on one type of nanogenerators – piezoelectric nanogenerators – aims at powering nanodevices and nanosystems using the energy harvested from the environment in which these systems are suppose to operate. This offers a completely new approach for harvesting mechanical energy using organic and inorganic materials. Researchers have now reported a novel bio-piezoelectric nanogenerator using naturally abundant, self-aligned cellulose fibrous untreated onion skin as efficient piezoelectric material. […]
