In strain\u2010mediated magnetoelectric heterostructures, however, efficient coupling depends strongly on crystallinity, interface quality, and mechanical boundary conditions. Epitaxial thin films provide excellent crystallinity and well\u2010defined interfaces, but substrate clamping suppresses strain transfer and limits magnetoelectric performance. Here, we report a freestanding magnetoelectric mesh based on an epitaxial BaTiO\n                    <jats:sub>3<\/jats:sub>\n                    \/CoFe\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    bilayer and demonstrate its use for magnetic\u2010field\u2010driven neural progenitor cell differentiation. By systematically relaxing the mechanical boundary condition from substrate\u2010clamped films to polydimethylsiloxane (PDMS)\u2010transferred structures and ultimately to freestanding meshes, we show a progressive enhancement in the magnetoelectric coupling coefficient. This enhancement is directly reflected in improved neural progenitor differentiation, establishing magnetoelectric transduction as a key driver of the observed cellular response. Our results show that engineering mechanical compliance in epitaxial magnetoelectric platforms can substantially improve biofunctional stimulation, providing a design strategy for next\u2010generation cell culture, differentiation, and wireless stimulation systems.\n
