An electromechanical actuator (EMA) includes: a stationary body portion; a movable body portion configured to move relative to the stationary body portion; an actuation element connecting the stationary body portion and the movable body portion and configured to actuate the movable body portion relative to the stationary body portion; a surface acoustic wave (SAW) sensor disposed on the actuation element; a first interface component disposed on the stationary body portion at an interface between the stationary body portion and the movable body portion; and a second interface component disposed on the movable body portion at the interface between the stationary body portion and the movable body portion. The second interface component is configured to transmit signals between the SAW sensor and the first interface component. The first interface component and the second interface component define an inductive position sensor to determine the position of the second interface component.
