摘要： A chip-scale vibrational energy harvester circuit may include magnets and coils with magnetic cores provided in proximity thereto. Either the magnets or the coils may be mounted on a micro-electromechanical spring system (MEMS) that is coupled to a stationary frame. The counterpart component may be mounted on the stationary frame. When the stationary frame experiences vibrational activity, the magnets and the coils may move with respect to each other, causing variations in the flux passing through the coils. The variations in the flux may induce voltages across the coils. The induced voltages may be rectified and stored as energy for later use.

The vias of the first contacting group are paired with a contact ring with contact points for electrically conductively connecting the first coil ends, in particular while forming a neutral point. The second coil ends are guided through the vias of the second contacting group, and a coil end portion or additional conductor element of the coil ends is azimuthally guided along the connection element and guided, preferably axially, out of the connection element while providing a three-phase winding connection at exposed positions.
