Optimization of dielectric elastomer wave power generation systems

Power generation devices using dielectric elastomers have attracted attention as renewable energy devices because they are highly efficient, stackable, easy to install, and inexpensive. Dielectric elastomers can also be used to create highly efficient actuators, sensors, and generators, without the use of rare earth elements. In particular, dielectric elastomer wave power generation devices have the advantage of not being restricted by wave direction or size, which are challenges in existing wave power generation applications. However, the greatest drawback is that it is not possible to create large dielectric elastomer membranes until now. In this study, the factors that improve the performance of dielectric elastomers from a perspective that has not been explored much until now were examined, and a method for simulating the power generation of dielectric elastomer generators with different electrodes was also examined. Furthermore, a double-action power generation test bench experiment was conducted in the laboratory, which enabled two power generation cycles with a single external force, thereby demonstrating the feasibility of this power generation method. Finally, the possibility of a larger dielectric elastomer wave power generation system is explored.
