Magnetoelectric composites with emergent properties for wireless and sensing applications (MECOMAP)
Financed by executive unit for financing education higher, research and development and innovation, CNCS – UEFISCDI, project number 263/2014, project code: PN-II-PT-PCCA-2013-4-1119
The aim of the present multidisciplinary project is to design by modeling&simulation, produce by innovative synthesis methods and various sintering strategies, to investigate the physico-chemical properties at various length scales of a few types of magnetoelectric composites with emergent properties in order to integrate them at industrial scale in a few types of new applications.
Two types of devices based on magnetoelectric composites will be produced: (i) miniaturised magnetoelectric tunable reconfigurable antennas based on particulate ceramic composites; (ii) new types of sensors / transducers / actuators / harvesters based on layered magnetoelectric composites.
The project will contribute to increase the consortium capacity to approach top research subjects in the field of smart multifunctional materials with high applicative potential. In terms of material science aspects, an important contribution will be given by a complex physico-chemical experimental – modeling approach for understanding the relationship between composition, micro/nanostructural parameters and functional properties of the magnetoelectric composites with different degrees of phase connectivity. The composition, phase interconnectivity and microstructures will be optimised and the best composite structures will be selected for the proposed applications. By considering the dielectric, ferro/piezoelectric and magnetoelectric properties of the produced composites, new magnetoelectric devices will be designed, realised, tested and optimised and the best solutions in terms of both technical parameters and cost efficiency will be implemented as prototypes by the industrial partner. The new devices are expected to contribute to the increase of the company performances by extending its production capacities, by extending the number of high specialised employees and the number of its beneficiaries.
The overall scientific goal is to improve the knowledge in the field of multifunctional magnetoelectric composite structures at different levels (macroscopic, mesoscopic and at nanoscale) in order to generate properties beyond the present ones and to integrate them into new magnetoelectric devices with superior characteristics and low cost.
