is a good example of photosynergetic effects. Further improvement of these systems
will be made possible by applying novel photochromic molecules, photochemical
processes, and assembled systems. In addition, cooperation with various fields, such
as robotics, information technology, and medical science, will lead to real application
as soft actuators.
