开发了新型凝胶系统，展示了类似于心跳的有节奏的脉动性机械运动。通过将pH和温度敏感的水凝胶与外部溶液介质中的非线性化学反应相耦合，实现了聚合物水凝胶的溶胀和溶胀自振荡。显示出周期性和节律性振荡的新型凝胶动力学可能为工作在动态振荡状态下的功能材料建立一个新的概念。
Novel gel systems demonstrating rhythmically pulsatile mechanical motion similar to that of a heartbeat were developed. Self-oscillations of swelling and deswelling for the polymer hydrogels were realized by coupling pH and temperature sensitive hydrogels with a non-linear chemical reaction in the external solution media. The novel gel dynamics exhibiting cyclic and rhythmical oscillations may establish a new concept for functional materials that work under dynamic oscillating states.
