Advanced sensing devices that can bring convenience to human life are what we pursue in nowadays industrial society. This work is devoted to fabricate a flexible magnetoelectric(ME) type proximity sensor, and also discuss in depth about the influence to output efficiency by different microstructures. The components of multi-phase ME structure is composed of magnetostriction and piezoelectric parts, utilizing pulse laser deposition(PLD) to deposit cobalt ferrite(CoFe2O4, CFO) and lead zirconate titanate(PbZr0.52Ti0.48O3, PZT) with different growth mechanisms, which leads to form 3 types of microstructure. The selection of substrate is another highlight to this study, with ME structure deposited on flexible muscovite, the performance of ME output efficiency (αE , mV/Oe*cm) can be improved, meanwhile, device itself can breakthrough space constraints and maximize the space usage. This article would first analyze the microstructure of samples, then measure the fundamental multiferroic properties, and finally test the performance and durability of device itself.
