Design and synthesis of organic and organic inorganic hybrid materials for mechanical energy harvesting applications

Abstract

Use of electronic devices has become an integral part of our day to day activities a major part of it is associated with storing receiving and sending information The domains of piezoelectricity and triboelectricity friction are two important phenomena which are majorly employed in harvesting mechanical energy through devices known as piezoelectric nanogenerators NG and triboelectric nanogenerators TENG The former one deals with mechanical impact vibration or deformation induced changes in electric polarization and the corresponding voltage and displacement current output The latter one deals with a real charge separation between two material systems driven by different frictional avenues Herein we describe the fabrication of piezoelectric triboelectric nanogenerators of polymer composites composed of organic inorganic materials and naturally occurring green precursors The present thesis deals with materials and device developments to harness store and apply mechanical energy around us newline newline
