WEARABLE TEXTILE-BASED PIEZOELECTRIC NANOGENERATORS WITH GRAPHENE/ZNO/AgNW

Abstract

While people are dealing with problems such as carbon footprint, water, air and environmental pollution and global warming caused by the use of traditional fossil energy sources, they have also faced the dilemma of energy crisis in search of alternative renewable energy sources. It is becoming more and more important to develop alternative energy sources such as wind, solar and tidal energy, renewable and clean energy. In addition to these, nanogenerators, which convert waste mechanical energy into electrical energy by physical interaction, have attracted great attention among innovative studies in recent years. Maintenance-free and flexible wearable nanogenerators using a sustainable power source are being developed for wearable/portable electronics. In this study, thermoplastic polyurethane coated nanogenerator fabrics containing graphene/ZnO/AgNw were developed for use in wearable electronics and the effect of zinc oxide concentration on the output power of textile-based nanogenerators was investigated. As a result, the nanogenerator produced with the mixture using 7% ZnO produced 10 mW of power, thus showing that ZnO-based materials can help the development of flexible piezoelectric TPU-based nanogenerators and advance to a new stage.
