“…The electrode uses carbon black, CNT, or nano-sized metal. At the material level, the DE actuator has a fast speed of response (over 100,000 Hz), with a high strain rate (up to 680%), as shown in Figure 3, a high pressure, and a power density of 1 W/g [32][33][34]. DEs can also be used for pressure-sensors and 3D position-sensors.…”

“…When the DE sheet is rolled, it becomes an actuator that looks like a human muscle. Figure 5 shows the roll actuators with 3-DOF [34]. As shown in Figure 6, a DE can be the arm or leg of a robot.…”

“…As shown in Figure 6, a DE can be the arm or leg of a robot. Using five of them, we created a robot that can moves around the surface of Mars [34], so it enables sideways stepping like a crab without turning around, when it collides with wall.…”

Dielectric elastomers (DEs) are lightweight and high-power, making them ideal for power control in a planetary exploration spacecraft. In this chapter, we will discuss the control of an exploration airplane exploring the surface of Mars using DEs. This airplane requires lightweight and powerful actuators to fly in the rare Martian atmosphere. DEs are a possible candidate for use as actuator controlling the airplane since they have high power, and high efficiency. A structural model of a wing having a control surface, a DE, and a linkage was built and a wind tunnel test of a control surface actuation using a DE actuator was carried out.

“…The drape weighs 4.6g and uses acrylic material # a. Carbon black, MWCNT (Multi-walled carbon nanotube), SWCNT (single-walled carbon nanotube) and high crystal CNT were used as electrode materials [54] The amount of power generated using carbon black was 284 mJ. However, changing the electrodes to MWCNT or SWCNT makes it possible to obtain more power, as shown in Table 2.…”

Power generation using dielectric elastomer (DE) artificial muscle is attracting attention because of its light weight, low cost, and high efficiency. Since this method is a system that produces electricity without emitting carbon dioxide nor using rare earths, it would contribute to the goal of environmental sustainability. In this paper, the background of DEs, the associated high-efficient wave energy generation (WEG) systems that we developed using DEs, as well as the latest development of its material are summarized. By covering the challenges we face and the achievements that we’ve reached, we can discuss the opportunities to build the foundation of a recycled energy society through the usage of these WEGs. On the other hand, to make these possibilities commercially successful, the advantages of DEs need to be integrated with traditional technologies. To achieve this, we also consider the method of using DEs alone and a system used in combination with an oscillating water column. Finally, the current status and future of DEGs are discussed.
