能够产生轴向收缩的纤维在自然界和工程应用中是常见的。尽管光纤驱动器有着广泛的应用前景，但如何制作出驱动应变大、响应速度快、功率密度高的光纤驱动器仍然是一个非常具有挑战性的课题。在这里，我们报告的液晶弹性体（LCE）微纤维致动器的制造使用一个简单的静电纺丝技术。由于LCE微纤维的尺寸非常小，它们可以以快速的响应速度产生大的致动应变（类似于60%）（
Fibers capable of generating axial contraction are commonly seen in nature and engineering applications. Despite the broad applications of fiber actuators, it is still very challenging to fabricate fiber actuators with combined large actuation strain, fast response speed, and high power density. Here, we report the fabrication of a liquid crystal elastomer (LCE) microfiber actuators using a facile electrospinning technique. Owing to the extremely small size of the LCE microfibers, they can generate large actuation strain (similar to 60 percent) with a fast response speed (
