US 2016/0111978 A1 · ELECTROSTATIC ENERGY HARVESTER WITH IMPROVED TRANSPARENCY AND MECHANICAL PROPERTY USING TWO-DIMENSIONAL MATERIAL ON FERROELECTRIC OR PIEZOELECTRIC MATERIAL

Abstract

Provided is an electrostatic energy harvester. A two-dimensionally structured material is transferred onto a ferroelectric or piezoelectric material layer, a property of the two-dimensionally structured material is controlled by poling performed on the ferroelectric or piezoelectric material to generate electric power generated by friction between the two-dimensionally structured material and a frictional charged material, and the electrostatic energy harvester has improved transparency and mechanical properties using the two-dimensionally structured material. According to the present invention, the two-dimensionally structured material is transferred onto the ferroelectric or piezoelectric material layer, the property of the two-dimensionally structured material is controlled by poling performed on the ferroelectric or piezoelectric material to generate electric power generated by friction between the two-dimensionally structured material and the frictional charged material, and the electrostatic energy harvester with improved transparency and mechanical properties using a two-dimensionally structured material is obtained.
