Photothermal Actuators: Photothermal Bimorph Actuators with In-Built Cooler for Light Mills, Frequency Switches, and Soft Robots (Adv. Funct. Mater. 27/2019)

In article number 1808995, Zunfeng Liu and co-workers develop a tri-layered bimorph actuator that shows a fast response, large bending amplitude, and small temperature change. Building on these advancements, a light-mill based on the wing-flapping mechanism upon light irradiation is designed.
