Localized strain profile in surface electrode array for programmable composite multiferroic devices

We investigate localized in-plane strains on the microscale, induced by arrays of biased surface electrodes patterned piezoelectrics. Particular focus is given to influence that adjacent electrode pairs have one another study impact densely packed arrays. present a series X-ray microdiffraction studies reveal spatially resolved micrometer-scale strain distribution. The maps with resolution highlight how local profile in square regions up 250 × μ m2 size affected are ferroelectric single-crystal [Pb(Mg1/3Nb2/3)O3]x-[PbTiO3]1−x. experimental measurements and simulation results show pair distance, positioning pair, including angle placement, neighboring arrangements strength direction regional strain. Our findings relevant development microarchitected strain-mediated multiferroic devices. could provide array-addressable control for applications straintronic memory, probabilistic computing platforms, microwave devices, magnetic-activated cell sorting platforms.
