- 요약Soft robotics have potential use in manufacturing, assembly, healthcare and other fields where interfacing with soft components requires care. Despite this, there are significant deficiencies in current soft actuator technologies that must first be overcome; liquid crystal elastomers (LCEs) may help bridge this gap. LCEs are like artificial muscle, capable of contraction and work density rivaling that of their natural counterparts while also standing apart from similar materials through their reversibility; through heat or light, LCE contracts, and in the absence of that stimuli, LCE relaxes to its original configuration, just like natural muscle. However, one limitation of LCE is the difficulty in interfacing it with electronics, which could augment their functionality and provide direct control. In this dissertation, the manufacturing and characterization of LCE actuators with enhanced electronic functionality is explored. The work is broken up into multiple parts, including (i) the characterization of a stretchable, conductive ink (ii) a multi-material 3D printing process developed to combine LCE and the conductive ink, and (iii) coaxial extrusion of LCE fibers with an electronic core for muscle-inspired actuation. This work developed advanced actuator composite systems and manufacturing methodologies that could lead to soft grippers capable of performing many tasks.
