An electrically controlled ultra-micromanipulator utilizes three sets of electrostrictive elements arranged in mutually perpendicular relationship and interconnected to selectively move a probe or other object in a three-dimensional pattern. In the disclosed embodiment, two sets of the electrostrictive elements establish pivotal movement about mutually perpendicular axes and the third set of electrostrictive elements establish linear movement in a direction perpendicular to the pivotal axes of the other two sets of elements. The elements establishing the linear movement are arranged in pairs adapted to flex in opposite directions upon an applied potential so that the probe or other object moves along a linear path.
