基础阶段：软物质力学¶
- 基本特征：小作用，大变化
杨氏模量 \(E < 1 \, \text{GPa}\)
介电高弹体¶
R. Pelrine, R. Kornbluh, Q.B. Pei, and J. Joseph, High-speed electrically actuated elastomers with strain greater than 100%. Science, 287: 836-839 (2000).
- 大于 \(100 \%\) 的变形
- 电能 & 机械能相互转化
- 缺点：需要高电压
水凝胶¶
Hydrogels: polymer networks infiltrated with a large amount of water
Soft, Smart, Structure-designable
- 双网络，力学性能很好的水凝胶
- 只能用一次
- J. Gong, Y. Katsuyama, T. Kurokawa, Y. Osada, Double-network hydrogels with extremely high mechanical strength, Advanced Materials, 15: 1155-1158 (2003).
- 离子键，可反复使用
