Berkeley Lab Researchers have developed an elegant and powerful new actuator that is smaller than the width of a human hair. This movie shows the microactuators flexing in response to a small voltage or a zap from a laser, both in air and underwater. Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are promising for microfluidics, drug delivery, and artificial muscles.
