Electro-thermal bi-stable actuator |
摘要 |
An actuator that uses electrothermal energy to switch between a first latching position and a second latching position. The actuator contains a leaf spring capable of latching into two distinct positions and two shape-memory wires. The shape-memory wires contract when heated and direct the leaf spring toward the two latching states. Once positioned in a latching state, the leaf spring will remain latched in that position until directed toward a different latching state by one of the shape-memory wires.
