Abstract
In recent years, self-oscillating gels are attracted attention as chemical actuators. Generally, in order to drive the actuator, the external device for controlling the stimuli such as temperature or electric field is required. On the other hand, living creatures have many phenomena that produces the constant rhythm autonomously without external control. The self-oscillating gels undergoes autonomous swelling- deswelling oscillation without any on-off switching by external stimuli. This process is produced by the chemical of the Belousov-Zhabotinsky (BZ) reaction in the polymer gel. We proposed a molding method for gels and demonstrated "self-moving gel" in one direction by introducting asymmetric shapes to the self-oscillating gel.
