Magnetoelectric Nanocomposites for Energy Harvesting and Sensing


The aim of this project is to investigate and develop materials and technologies utilizing the Magnetoelectric Effect (ME) for energy harvesting. Miniaturized energy harvesters have attracted considerable interest for e.g. self-powered implantable Microsystems and Nanosystems or wireless devices and sensors. 
Magnetoelectric (ME) materials become magnetized when placed in an electric field and electrically polarized when placed in a magnetic field. This effect can occur in single phase materials but requires special lattice symmetry conditions. Yet, the ME effect obtained in composites is more than a hundred times that of single-phase ME materials. In recent years, thin film ME composites have attracted great interest due to their unique advantages compared to bulk composites. By combining piezoelectric and magnetostrictive films, the potentialities of ME materials are increased. This way, totally new concepts can be provided in the field of microtechnology with additional functionalities.
