Abstract Scope |
This investigation employs high-fidelity finite element modeling to investigate the direct magnetoelectric (ME) effect in cobalt ferrite (CFO):barium titanate (BTO) composites with distinct connectivity configurations (0-3 particulate and 2-2 laminate). The simulations reveal pronounced anisotropy in ME coupling, with maximum coefficients occurring when the magnetic field vector is aligned with the magnetostrictive phase's primary axis. The model effectively captures the nonlinear magnetostrictive behavior within the CFO component, exhibiting strong correlation with experimental measurements. Furthermore, we explore inkjet printing as a precise additive fabrication approach for ME composites, enabling controlled distribution patterns of particle films. A comprehensive parametric analysis quantifies the influence of critical variables including nanoparticle size, interfacial contact area, and deposition morphology (particularly ‘coffee ring’ formations) on coupling efficiency. These findings establish a predictive framework for ME composite optimization while demonstrating inkjet printing's viability as a scalable route for fabrication of next-generation sensors, actuators, and energy harvesting devices with enhanced performance characteristics. |
