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. ## Claims ### Claim 1 A drive device, comprising: a component carrier which comprises a stack comprising 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 arranged at least partially in the cavity and configured for being drivable to move relative to the component carrier, wherein the driven body is plate-shaped; at least one drive coil for creating a magnetic drive field; at least one drive magnet arranged for interacting with the magnetic drive field created by the at least one drive coil to thereby generate a force for moving the driven body relative to the component carrier; wherein 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. ### Claim 2 (depends on 1) The drive device according to claim 1, wherein the at least one drive coil forms part of the component carrier and the at least one drive magnet forms part of the driven body. ### Claim 3 (depends on 1) The drive device according to claim 1, wherein at least part of the at least one drive coil forms part of the at least one electrically conductive layer structure. ### Claim 4 (depends on 1) The drive device according to claim 1, wherein the at least one drive coil is embedded and/or formed in the component carrier. ### Claim 5 (depends on 1) The drive device according to claim 1, wherein the at least one drive magnet is embedded in the driven body. ### Claim 6 (depends on 1) The drive device according to claim 1, wherein the driven body includes substantially parallel opposing main surfaces adjacent to the at least one drive magnet and the at least one drive coil forming part of the driven body. ### Claim 7 (depends on 1) The drive device according to claim 1, wherein the driven body is configured for being driven to rotate relative to the component carrier. ### Claim 8 (depends on 1) The drive device according to claim 1, wherein the driven body is configured for being driven to move linearly, to reciprocate, relative to the component carrier. ### Claim 9 (depends on 1) The drive device according to claim 1, wherein the at least one drive magnet is a permanent rare earth magnet. ### Claim 10 (depends on 1) The drive device according to claim 1, comprising at least one of the following features: wherein the driven body is arranged entirely in the cavity or partially extends beyond the cavity; wherein the driven body is configured to temporarily move at least partially out of the cavity, for mechanically actuating an external entity, when said force for moving the driven body relative to the component carrier is exerted; at least one component on and/or in the driven body and being configured for generating electric operation energy based on the magnetic drive field. ### Claim 11 (depends on 1) The drive device according to claim 1, further comprising: at least one bearing by which the driven body is movably mounted on the component carrier, wherein when the at least one bearing comprises a mechanical bearing the mechanical bearing is in the component carrier. ### Claim 12 (depends on 11) The drive device according to claim 11, comprising at least one of the following features: wherein the at least one bearing comprises a magnetic bearing comprising cooperating attractive, bearing magnets of the component carrier and of the driven body; wherein the at least one bearing comprises a mechanical bearing or a friction bearing; wherein the at least one bearing is configured for disabling a mutual vertical motion between driven body and component carrier; wherein at least one of the at least one bearing is configured for acting laterally; wherein at least one of the at least one bearing is configured for acting vertically. ### Claim 13 (depends on 1) The drive device according to claim 1, comprising at least one of the following features: wherein windings of the at least one drive coil are circumferential horizontal electrically conductive structures being vertically stacked within the component carrier and being interconnected by vertical electrically conductive structures; comprising a drive shaft extending through the component carrier and through the driven body and being configured for moving together with the driven body and relative to the component carrier; wherein the cavity has an opening on at least one side.
