Abstract
A method for post-fabrication modification of the snap actuation properties of a thermally responsive bimetallic actuator by exposing a pre-formed bimetallic actuator to laser energy, thereby permanently altering the thermal response properties of the bimetallic actuator, and a thermally responsive bimetallic actuator having snap actuation properties developed according to the method.
