Abstract
An apparatus for and method of conditioning a thermally activated shape memory alloy wire for use in an application, wherein the apparatus includes an adjustable hard-stop and the preferred method includes pre-determining a minimum activating current, allowable strain, and a loading magnitude and form based on the wire configuration and application, and further includes applying a double-exponential model to determine a final recoverable strain over fewer cycles.
