3. Miniature planar transformer with circular spiral winding and hybrid core—ferrite and magnetic nanofluid designed for new energy harvesting systems

One of the novelties of the future harvesting devices is regarding the use of a magnetic liquid core micro-transformer for the DC-DC converter of the harvesting device. From the operating point of view, by replacing the solid core with a hybrid core—ferrite and magnetic nanofluid, we estimate to result in a better heat dissipation and a reduction the thermal stresses in the microtransformer leading to a longer life cycle of the device, maintaining or even improving the electric characteristics. Also, the dielectric properties of the micro-transformer will be improved.
