Preface
The conventional motors driven by the electromagnetic force have been playing and will play the most important roles in motion control of automated machines like robots. However, for the advanced machines and instruments with higher performance, the conventional motors seem to be difficult to satisfy the coming sophisticated demands. And new outstanding actuators are expected to cause technological innovations in such broad fields of their applications as industry, basic science, medicine, welfare, and global environment. So, the development of innovative actuators is recognized as one of the most important key technology for next generation. In accordance with the requirement, the five year national research project “Next-Generation Actuators Leading Breakthroughs” was organized and granted by Ministry of Education,
