Developing Spring-Roll Dielectric Elastomer Actuator System Based on Optimal Design Parameters

To develop a well designed practical spring-roll dielectric elastomer actuator system, we have to optimize its design parameters. In our pervious work, we have achieved the design parameters without taking the applied voltage required to activate the actuator into consideration because the applied voltage might change the optimal design parameters. In the paper, optimal design parameters have been achieved and decreased the applied voltage and the problems of high voltage are avoided. Furthermore, a voltage supply that is able to pump enough controlled charges to the actuator system is developed. A switched based multistage charge pump driven by a controlled low voltage switching power supply and a voltage driver is also proposed. The recently developed voltage supply is characterized by a wide range of controlled voltages. The achieved results based on the proposed approaches show that the design of the actuator is getting simpler and outperforms compared with the other related approaches.
