科学领域:

材料科学材料科学材料科学
聚合物科学聚合物科学
机器人技术机器人技术机器人技术

背景情况:

液晶弹性体 (LCE) 对执行器来说是有希望的,但通常需要外部加热或光线.
现有的电活性LCE是有限的,通常是单功能 (曲或收缩).

研究的目的:

开发一种能够同时曲和收缩的双功能电动LCE (eLCE).
为了提高性能,将LCE技术与离子电活性聚合物设备 (i-EADs) 结合起来.

主要方法:

通过集成LCE和i-EAD来制造三层ELCE.
应用低压刺激 (±2V在0.1Hz) 来通过氧化还原行为和离子运动诱导曲.
施加更高的电压 (±6V在10Hz) 通过焦尔加热触发肌肉类收缩.

主要成果:

在±2V刺激下,达到0.80%的曲应变差.
经过±6V刺激,证明了类似肌肉的线性收缩,达到20%的应变.
这使得eLCE能够以20%的应变和5.38 kJ·m−3.3的工作能力提升270倍的重量.

结论:

新型三层eLCE在低压控制下表现出双功能执行 (曲和收缩).
这种方法集成了LCE和i-EAD技术,用于多度自由度的智能材料.
开发的eLCE显示了软机器人,电子设备和传感器的巨大潜力.
