A New Design Method of Servo-actuators Based on the Shape Memory Effect

Summary: The possible realization of micro-actuators driven by the shape memory effect is discussed. The mechanism, specifications and requirements of the shape memory effect as applied to robot actuators are investigated. A theoretical model is developed that can simulate the thermoelastic and kinematic transformations associated with the shape memory effect. By using a new design configuration, a prototype SMA actuator has been realized.
