| Outline of Final Research Achievements |
“Self-oscillating” polymer gels that undergo spontaneous cyclic swelling-deswelling changes without any on-off switching of external stimuli, as with heart muscle, were developed by the researcher. The self-oscillating gels were designed by utilizing the Belousov-Zhabotinsky (BZ) reaction, an oscillating reaction as a chemical model of self-organization in living systems. Self-oscillation in several scales such as contraction and expansion of polymer chain, aggregation and disaggregation of polymer micelle and vesicle, sol-gel transition of polymer solution, volume changes, peristaltic motion, were realized. Potential applications of the self-oscillating polymers and gels include several kinds of functional material systems such as biomimetic actuators, mass transport systems and functional fluids, e.g., artificial cilia, artificial amoeba, artificial cell, artificial heart muscle, artificial transport tube, autonomous soft actuator (soft robot).
