“…For example, the skin color of the chameleon changes according to external stimuli, and the leaves of the mimosa close when touched by the outside world. [14][15][16] Inspired by these phenomena, scientists have designed many stimuli-responsive materials whose physicochemical properties can be modulated with the change in the external environment, such as pH, 17,18 temperature, 19,20 light, ultrasonic waves, and magnetic elds. [21][22][23][24] These stimuli-responsive materials are used in drug delivery, sensors, articial muscles and other elds widely.…”
