A piezoelectric triboelectric hybrid wearable nanogenerator and its preparation method

Abstract

The invention discloses a piezoelectric friction electric hybrid wearable nano generator and a preparation method thereof. The core is that a non-woven fabric having piezoelectricity and a nanowire-coated microsphere secondary micro-nano structure is prepared. Spinning liquid is directly spun into the non-woven fabric with the secondary micro-nano structure by a self-assembled far-field electrospinning and high-speed wire collection method. The non-woven fabric and other materials are assembled into the piezoelectric friction electric nano generator. The hybrid nano generator includes a firstelectrode, an elastic friction layer, a piezoelectric friction electric active layer, a second electrode, a high-molecular polymer supporting layer, an adhesive layer and a wire. The nano generator isa wearable device. The piezoelectric friction electric hybrid wearable nano generator is simple in preparation process, easy to operate and low in cost, and can be massively produced.

Description

technical field The invention relates to the technical field of nanomaterials, in particular to a piezoelectric triboelectric hybrid wearable nanometer generator and a preparation method thereof. Background technique With the continuous consumption of various non-renewable energy sources, the energy crisis has become a worldwide problem. The importance of developing green and renewable energy has become increasingly prominent. Compared with various renewable energy sources, mechanical energy exists widely in various forms, such as mechanical vibration, wave surge, water flow, human body movement, wind blowing, sound wave vibration, etc., all contain large or small mechanical energy. Piezoelectric nanogenerators (PENG) and triboelectric nanogenerators (TENG) can extensively harvest these energies. Compared with other renewable energy sources such as photovoltaic power generation, wind power generation, and tidal power generation, PENG and TENG have the advantages of being n...
