Humidity‐ and Photo‐Induced Mechanical Actuation of Cross‐Linked Liquid Crystal Polymers

Azobenzene‐containing cross‐linked liquid crystal polymer films without hydrophilic groups exhibit dual‐responsivity to humidity and UV light. The films realize not only a series of large and sophisticated contactless motions by utilizing moisture, including an inchworm walk, and tumbling locomotion, but also dual‐mode actuation that can be applied in flexible electronics.
