Classification: CPC H | IPC H

Claim 5:
6. An energy harvesting apparatus using an electroactive material, the energy harvesting apparatus comprising:
an electricity generator including the electroactive material to generate a voltage due to deformation by an external stimulus; and
an impact generator including a deformable and restorable material capable of repetitive deformation and restoration and configured to generate in the electricity generator a dynamic behavior based on the repetitive deformation and restoration,
wherein a stimulus by the impact generator to the electricity generator enables energy harvest, wherein the electricity generator comprises:
a first film layer located to face the impact generator, including the electroactive material, and manufactured in a film form; and
a second film layer located on a side of the impact generator opposite to the first film layer, including the electroactive material, and manufactured in a film form,
wherein the impact generator comprises unit impact units arranged in a lengthwise direction of the electricity generator so that a multi-point stimulus is enabled in the electricity generator, and
each of the unit impact units comprises a deformation part capable of repetitive deformation and restoration, and a sliding part that causes friction with the second film layer by sliding according to deformation of the deformation part.
