Abstract
In a method of controlling a gaze direction of a camera, the camera is placed on a top surface of a substrate that is pivotally coupled to a frame, wherein a movement arm depends downwardly from the substrate. The movement arm is moved with two spaced apart amplified piezoelectric ceramic stack actuators that are affixed to the frame and coupled to the movement arm by deforming the amplified piezoelectric ceramic stack actuators as a result of applying a voltage thereto, thereby changing an angular orientation of the substrate.
