he wave power generation has attracted attention as one of useful utilization
methods for ocean energy. However, the conventional wave generators are
large, expensive and unable to efficiently generate electric power with small
amplitude waves limiting their widespread usage. To solve these problems, we
would discuss the possibilities for a wave power generator using dielectric
elastomer (DE) recently developed as a novel method for harvesting renewable
energy. DE is a new smart material technology with characteristics and properties
not seen in other materials. The basic element of DEs is a very simple structure
comprised of thin polymer films (elastomers) sandwiched by two electrodesmade
of a stretchable material. DEs can operate as an electrically-powered actuator.
When a voltage difference is applied between the electrodes, they are attracted
to each other by electrostatic forces leading to a thickness-wise contraction and
plane-wise expansion of the elastomer. The use of a DE actuator in the reverse
mode, in which deformation of the elastomer by external mechanical work is used
to generate electrical energy, has been gaining more attention. As DE is very light,
inexpensive, and easily formed into multiple layered structures, it can make a very
simple and robust direct drive wave power system that is economically viable.
DE has moved now from the research and development stage to the commercial
domain with research and development on practical applications and furthermore
to the mass production stage
Biography
Seiki A Chiba was Executive Director for advanced R&D project
development, Stanford Research Institute (SRI International).
He served SRI for 22 years. He was supervising advanced R&D
programs including Japanese Government projects. Currently,
he is serving as CEO and Professor at Chiba Institute of Science.
