Fig. 28.12 Example sites where DE generator systems could be installed
(i) Tanker equipped with DE: It allows the ship to sway safely and always
travel safely (Waki and Chiba 2017)
(2) Ultra large DE system which installed in the ocaen
(j) Wave Generators in Ocean (Chiba et al. 2008, 2017a)
(k) Hydrogen Production Plant (Chiba 2019c).
28.4 Promotion of Various Types of Green Technology
DE sensors are flexible, inexpensive, accurate, efficient and can be used anywhere,
making them ideal. Since the sensor itself can generate electricity, batteries are
unnecessary and it is possible to construct various kinds of global sensor systems.
In this section, we will briefly discuss the following items:
(1) The motors or engines of vehicles, trains, etc. could be replaced with DE motors.
Existing factory robots could also be replaced with DE actuators.
(2) Global environmental measurement for accurate predictions using DE sensors
(3) DE sensors can also monitor the quality of water supplies and sewerage
continuously, and can generate electricity with hydraulic power.
28.4.1 DE Motors
As mentioned in the section introducing the background of DEs, 0.15 g of DEs can
lift a weight of up to 4 kg. Compared with the performance of dielectric elastomers,
existing motors and actuators driven by air, dielectric elastomers have a very high
output per unit weight, high driving speed, and very low power consumption (Waki
