Many physiological systems maintain rhythmical oscillations under constant environmental conditions, and act in a drynamic nonequilibrium state, as represented by the autonomic heartbeat, brain waves, periodic hormone secretion. We have attempted to construct such a biomimetic energy transformation system generating spontaneous and periodical motion of polymer chains from the chemical energy. As a source of chemical energy, the Belousov-Zhabotinsky (BZ) reaction was used.
