Multi-directional actuation by a single stimulus is highly required in applications such as sensors, actuators and soft robotics. Liquid crystal elastomers (LCEs) are one of the most promising materials for the soft-actuator due to their capability of stimuli-responsive shape morphing, that is able to be predesigned LC molecular orientation. Here, we report an effective approach to the multi-directional curvature reversal by a single stimulus, heat, using monolithic Liquid crystal elastomers (LCEs). The shape morphing of the LCE actuator exhibits highly reversible and fast actuation by heating and cooling, allowing new concept of a practical application: a self-regulated valve that is capable of qualitatively sorting liquids by temperature. |
