Ultra-High Sensitive Magnetoelectric Nanocomposite Current Sensors

Abstract

Sintered magnetoelectric composites generally exhibit reduced sensitivity due to: 1) breakage and aggregation of ferrite coating during compaction forming path of reduced resistivity, 2) coarsening of piezoelectric particle leading to interfacial porosity, and 3) inter-diffusion between piezoelectric and ferrite resulting in coherency loss. In order to overcome these problems, we are adopting following approach to synthesize core-shell nanocomposites: 1) create piezoelectric particles (sub-micron range) with crystallographic facets which will result in uniform stress.
