Theoretical optimization of magnetoelectric multilayer laminates

Magnetoelectric (ME) materials are becoming increasingly relevant in the development of new technologies for biomedical applications, sensors and actuators, among others. Mathematical models simulations allow to optimize features acquire fundamental knowledge on material properties achieve innovative developments devices. In this way, work is focused simulation both polymer-based ceramic-based ME laminates, order evaluate influence their structure, mechanical, electrical magnetic response. The effect size configuration has been evaluated Vitrovac/poly (vinylidene fluoride)(PVDF) Vitrovac/lead zirconate titanate (PZT) laminated composites. It established that elastic amorphous constitution PVDF key parameters governing its response, increasing with number layers composite. Good agreement when comparing trends reported experimentally literature, presenting a curve rapidly increases αunit thickness ratio up n = 0.3, saturation reached. Further, an optimal PZT multilayers found, external magnetostrictive phases above 0.2, leading response 86.7 V/cm. Finally, it configurations (M-M configuration) show more stable behaviour (without observation random peaks) over different layers, about 11.5 V/cm, while P–P present regions peaks, out expected trend (48 V/cm) closer one obtained ceramic multilayers.
