Classification: CPC H | IPC H

Claim 0:
1. 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 impact generator comprises a plurality of deformation parts arranged to correspond to an entire area of the electricity generator so that a multi-point stimulus is enabled in the electricity generator, the deformation parts including the deformable and restorable material
wherein the impact generator has a snap dome structure including the deformation parts that are turned over when a threshold load or more is applied thereto, and a connection part configured to connect the deformation parts adjacent to each other, and
wherein locking holes are formed in one of connection parts that connect the adjacent deformation parts to each other, and locking pins are formed in the other, so that the adjacent deformation parts are connected to each other through locking between the locking holes and the locking pins.
