Abstract
A kelp-inspired marine energy converter (MEC) device having a plurality of strips of flexible electroactive materials connected to a power conditioning module and anchored to a structure (such as the ocean floor) is described. The movement of the strips caused by water motion or current action (i.e., water motion) converted by the electroactive material to electrical energy.
Claims15
A device for generating electrical energy from a water motion, the device comprising:
- a strip having a first end, a length, and a second end;
- a first buoyancy device connected to the second end;
- a second buoyancy device connected to the length;
- and
- a power conditioning module;
- wherein:
- the strip, the first buoyancy device, the second buoyancy device, and the power conditioning module are submerged;
- the strip comprises an electroactive material, a first electrode, and a second electrode,
- the electroactive material comprises a positive surface and a negative surface,
