Energy harvesting device combined with self-powered touch sensor

摘要

Disclosed is a self-powered touch sensor combined energy harvesting device capable of sensing the pressure caused by a touch from the outside without external power and harvesting and storing energy generated when the pressure is caused by the touch. The disclosed self-powered touch sensor combined energy harvesting device is disposed on a first substrate having a first electrode, a second substrate having a second electrode, an energy generating layer disposed on the first electrode, and a second electrode, And an elastic layer disposed to face the energy generating layer, wherein the energy generating layer may include a piezoelectric film that generates electricity by pressure or an electrostatic film on which a surface is charged with electric charge.
