  • Feedback control for shape memory alloy actuators
    Patent number: 8706305
    Abstract: Control feedback for regulating strain output of a shape memory alloy (SMA) actuator using a stress sensor for outputting an indication of a mechanical resistance applied against the SMA actuator, and a state sensor for outputting an indication of a state of actuation of the SMA actuator has been found to be surprisingly accurate. Advantageously feedback detection can be provided with sensors that have low power requirements and can be controlled with simple electronics.
    Type: Grant
    Filed: February 20, 2009
    Date of Patent: April 22, 2014
    Assignee: Canadian Space Agency
