  • Antagonistically actuated shape memory alloy manipulator
    Patent number: 9744055
    Abstract: An antagonistically actuated shape memory alloy (SMA) manipulator utilizes a pair of SMA actuators. The SMA actuators are configured, such that one actuator is trained to have a substantially linear or extended shape in its austenite phase, while the other actuator is trained to have a curved or flexed shape in its austenite phase. As such, the manipulator is operated, such that when one SMA actuator is heated and takes on its “trained” shape in the austenite phase, the other SMA actuator is permitted to cool and allowed to return to its original “untrained” shape in the martensite phase, and vice versa. This antagonistic operation of the SMA actuators allows the manipulator to achieve rapid flexion and extension movements.
