Abstract
A mechanical actuator is disclosed. The mechanical actuator can comprise an interface portion configured to interface with an object, a spring configured to exert a force on the interface portion, and a shape memory member coupled to the interface portion. The shape memory member can be configured to fracture at a predetermined temperature range. Upon fracture of the shape memory member, the force of the spring can cause the interface portion to act on the object.
