Abstract
A micro-electromechanical actuator includes a pair of elongate layers capable of being heated with an electrical current to thermally expand and to perform work. A pair of spacers separates the elongate layers from each other. The spacers are arranged at respective opposite ends of the elongate layers and are fast with the layers so that the actuator is deflected when one of the layers is heated.
