Challenge of creating high performance dielectric elastomers

摘要

A DE capable of the high speed and high output required for driving robots and automobiles is still under study. Chiba et al succeeded in raising and lowering a 4kg weight by about 1mm at a speed of 97msec using a total DE weight of 0.98g last year. The DEA used a VHB4910 and SWCNTs. For the above purposes mentioned above, however, the current weight able to lifted is insufficient. We examined various elastomers (including materials newly developed) and various electrode materials, and we succeeded in lifting a weight of 8 kg quickly. We also considered the potential of this DEA as a drive source for electric vehicles and a potential for power generation from the vehicle’s movement.
