ABSTRACT:
An actuating device includes: at least one first elongated member having a first coefficient of thermal expansion (CTE); and at least one second elongated member having a second CTE different from the first CTE, the second elongated member being nested within the first elongated member, the device being configured to displace a portion of the device a selected distance along a major axis of the device based on a relationship between the first CTE and the second CTE in response to a change in temperature.
