The thermoresponsive behavior of LCE microstructures were inves�gated within a hea�ng stage (LTS 420, Linkam Scien�fic Instruments), which was either coupled to the op�cal microscope DM2700 or a stereomicroscope (Leica Z16 APOA, equipped with a camera EO-5310). The hea�ng cycle was programmed to have the temperature first be sprint up from ambient temperature to 120°C (35°C/min), followed by a steady gradient un�l 300°C (10°C/min), and then remained constant for 5 minutes before cooling down to room temperature with the same temperature gradient.
