Abstract
A linear actuator associated with an actuator system for a device includes a wire cable fabricated from an active material. The linear actuator couples to the device and to the moveable element. The active material induces strain in the linear actuator in response to an activation signal. The linear actuator translates the moveable element relative to the device in response to the induced strain. An activation controller electrically connects to the linear actuator and generates the activation signal. A position feedback sensor monitors a position of the moveable element.
