Abstract
A drive device includes a component carrier with a stack having at least one electrically conductive layer structure and/or at least one electrically insulating layer structure and a cavity formed in the stack. A driven body is arranged at least partially in the cavity and configured for being drivable to move relative to the component carrier. At least one drive coil for creating a magnetic drive field and at least one drive magnet interacts with the magnetic drive field created by the at least one drive coil to generate a force for moving the driven body relative to the component carrier. One of the at least one drive magnet and the at least one drive coil forms part of the component carrier and the other one of the at least one drive magnet and the at least one drive coil forms part of the driven body.
