  • Electrostatic energy harvester with improved transparency and mechanical property using two-dimensional material on ferroelectric or piezoelectric material
    Patent number: 10003281
    Abstract: 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.
