摘要: Novel gel systems demonstrating rhythmically pulsatile mechanical motion similar to that of a heartbeat were developed. Self-oscillations swelling and deswelling for the polymer hydrogels realized by coupling pH temperature sensitive with non-linear chemical reaction in external solution media. The novel dynamics exhibiting cyclic rhythmical oscillations may establish new concept functional materials work under dynamic oscillating states.
