Abstract

Disclosed herein are flexible wave energy converters that actuate electrical generators with dynamic strain (e.g., flexing, stretching, twisting, distension) to convert wave energy to electrical energy. The flexible wave energy converter utilizes flexible electric generators embedded throughout the wave-energy converter's flexible body.

First claim

The invention claimed is:

1. A device for converting a stress from an ocean wave to electrical current, the device comprising:
a body having a first side, a second side, and a base; wherein:
the body comprises a flexible material and a plurality of elastomer generators and is configured to receive the stress which compresses the first side, resulting in a compressed first side and stretches the second side, resulting in a stretched second side,
at least one fin is attached to the first side and is configured to receive the stress from the ocean wave,
the base is configured to connect the body to a stable horizontal surface and is configured to remain relatively immobile when the body receives the stress from the ocean wave, and
the compressed first side and the stretched second side are configured to stretch and compress the plurality of elastomer generators, resulting in conversion of the stress from the ocean wave to electrical current.

2. The device of claim 1 , wherein the plurality of elastomer generators comprises:
an ionic dielectric elastomer generator;
a layered reinforced dielectric elastomer generator; and
a structural reinforcement; wherein:
the structural reinforcement has a first surface and a second surface,
the ionic dielectric elastomer generator is in contact with the first surface, and
the layered reinforced dielectric elastomer generator is in contact with the second surface.

3. The device of claim 2 , wherein the structural reinforcement is carbon fiber.

4. The device of claim 1 , wherein:
the flexible material further comprises a polymer, and
the plurality of elastomer generators are implanted within the polymer.
