Caption: A pulse of laser light can induce the microactuator to flex. In this microscope image, a palm-like array of actuators flex one at a time (top panel) or all at once (middle panel). The lower panel shows individual fingers flexing underwater -- a capability that makes the device suitable for biological applications.
