要約(日本語): Comparison with Existing Wave Power generators and Artificial Muscle Generators The establishment of an energy system that uses renewable energy is attracting attention as a possible answer to clear our existing energy problems. This article presents a discussion on one energy harvesting method that has been the focus of attention recently: the generation system based on electroactive polymer artificial muscle (EPAM). When a voltage is applied to the polymer film, the (dielectric) polymer stretches by the effect of the Coulomb force, and it goes back to its original shape when the voltage is stopped. By reversing this operational cycle, it is possible to generate electricity. That is, compressing the polymer film by any method generates electrostatic energy and the film itself becomes a condenser. There are a water or marine turbine generators, which can be used inland or ocean. The use of conventional devices required a converter to transform the water or marine turbine rotation into higher-speed rotation of the generator. However, a water mill or wave generator using EPAM does not require high-speed rotation from a converter, and a simple structure that induces deformation in the EPAM is enough to generate electricity with high efficiency.Based on data from our ocean experiments, the generation efficiency was calculated to be in the order of 20 US cents/kWh. In the near future, a sheet of 1 m2 in area could generate twice this amount of energy and have double of the useful life, making the estimated efficiency to be in the order of 4.5-7 US cents/kWh.
