Actuator formed of thermally adaptive material and a thermoelectric junction

An actuator, comprising:

• an actuator body extending between an actuator top and an actuator bottom, a top actuator support located at the actuator top and a bottom actuator support located at the actuator bottom,
• wherein the actuator body includes:
• a wall defining an outer boundary and extending longitudinally from a first end to a second end and transversely from a first side to a second side,
• wherein:
• the wall is nonmetal;
• the wall defines:
• a first segment extending longitudinally between the first and second ends and transversely from the first side to a segment junction;
• and
• a second segment extending longitudinally between the first and second ends and transversely from the second side to the segment junction,
• wherein the first and second segments are formed of thermoplastic;
• a thermoelectric junction is disposed around the outer boundary or between the first and second segments;
• and
• wherein:
• the first segment is formed of a first material having a first coefficient of thermal expansion (CTE);
• the second segment is formed of a second material having a second CTE that differs from the first CTE;
• first fibers having the second CTE are embedded in the first segment;
• and
• second fibers, formed of a third material that differs from the first and second materials, and has a third CTE that differs from the first and second CTE, are embedded in the second segment,
• whereby the wall defines a transverse CTE gradient.
