ABSTRACT:
A drive device formed by etching a wafer. The drive device includes a drive element that can sequentially mesh with a driven element and an actuating element that can displace the drive element according to a hysteresis movement thereby driving the driven element. Placement of the drive element on an outer edge of the wafer enables an interfacing of the drive element with a driven element placed opposite therefrom. A clockwork mechanism including a drive device of the aforementioned type and an input gear that can be rotationally driven by the drive device is also provided.
