Abstract:
A smart material actuator wherein one or more smart material devices are constrained in a frame such that expansion or contraction of the frame effects movement of side frame members away from or towards one another. The side frame members are constrained such that such movement away from or towards one another effects rotational movement of the frame for outputting amplified movement at an output member that rotates with the frame.
