| Abstract Scope |
Magnetic field sensors are very useful considering the technological domains, with the magnetoelectric effect emerging as a promising avenue for achieving high-sensitivity sensor capabilities. Yet, the assembly of magnetoelectric sensors, particularly those relying on sintered magnetoelectric composites, has encountered complications due their elevated electrical conductivity, which constrains their technological utility. This study aimed to surpass these challenges through a uncommon synthesis approach to arrange cobalt ferrite nanoparticles/lead zirconate titanate (PZT) fibers/polymer composites. The characterization of these composites entails the application of scanning electron microscopy to elucidate their microstructural complexity, alongside dielectric measurements aimed at evaluating their electrical characteristics. Magnetoelectric measurements were used to probe the distinctive magnetoelectric effect manifested within the composites. Notably, the application of magnetic fields generated electric responses, thus supporting the feasibility and efficacy of magnetoelectric sensors facilitated by these composite materials. |
