Abstract Actuators utilizing snap‐through instabilities are widely investigated for high‐performance fast actuators and shape reconfigurable structures owing to their rapid response limited reliance on continuous energy input. However, prevailing approaches typically involve a combination of multiple bistable actuator units achieving multistability within single unit still remains an open challenge. Here, soft is presented that uses memory alloy (SMA) mixed‐mode elastic achieve intrinsically...
Recent work on battery-free soft robotics has demonstrated the use of liquid crystal elastomers (LCE) to build shape-changing materials activated by applied external heat. However, sources heat must typically be in direct field-of-view robot (i.e. NIR, laser, and visual light EM or convective heats guns), tethered an power supply thermoelectric heating resistive joule heaters), require a heavy on-board battery that limits mobility range. This paper presents novel soft-robotics platform can...
Liquid crystal elastomers (LCEs) are becoming increasingly popular as a shape memory material for soft robot actuators that operate in contractile or flexural mode. There have been previously studies on the use of LCEs reversible changes surface topography. However, protrusions typically limited to order 1 μm depend light, heat, electrical stimulation difficult locally control require relatively high voltage. This article presents novel operation mode LCE based wrinkling behavior an...
