Abstract
Magnetoelectric (ME) effect occurs when a change in magnetic field triggers stress in the magnetostrictive material which is then transferred to an adjacent ferroelectric material which generates voltage under direct piezoelectric effect. This product effect enables several sensing and energy harvesting applications. In this talk, we will present an overview of research on magnetoelectric phenomenon within nanoscale through bulk scale and explain the working principle of devices and systems. Particularly, we discuss advances in particulate ME composites, laminate ME composites, 3–1 ME composites. We also present development of piezoelectric and magnetostrictive composites as well as design and fabrication of ME devices. This study demonstrates importance of material selection, design of devices and its applications such as gradiometer and energy harvester.
