Energy harvesting device having self-powered touch sensor

Abstract

Provided is an energy harvesting device having a self-powered touch sensor so that the energy harvesting device is capable of sensing pressure due to an external touch without using external power and harvesting and storing energy generated in response to the touch pressure. The energy harvesting device includes first and second electrodes facing each other, an energy generation layer disposed on the first electrode, and an elastic layer disposed on the second electrode layer, the elastic layer facing the energy generation layer and being configured to be elastically deformed according to pressure applied to the elastic layer. The energy generation layer is configured to generate energy according to the pressure applied to the energy generation layer.

Dependencies are inferred from the claim text.
