Abstract
Rapid internal cooling of shape memory effect material actuators during cooling portion of thermal cycle by means of embedded micro-heat pipes enables one, two and three dimensional actuators comprised of composite structures with rapid response times. Structures are able to operate in high-temperature environments, have low thermal hysteresis, have improved positional control for robotics applications and enable large scale shape memory effect material actuators with rapid response characteristics.
