Soft Ferrite Pressure Sensors: Study 2 (Fein & Barrett): The Villari Effect: Pressure vs. Inductance Functions for Potential Soft Ferrite Pressure Sensors

Institution

Northern Kentucky University

Abstract

Reverse Magnetostriction, or the Villari Effect, was analyzed by applying increasing pressure on toroidal bodies. When wrapped in thin conducting wire and current passed through, the inductance may change and thus a pressure sensor can be fabricated. Functions of this inductance vs pressure change are however necessary to create such a sensor. A vibrating sample magnetometer measured initial permeability of the bodies and Scanning-Electron Microscopy was used to study the microstructure both before and after testing. A linear response and eventually a function of linear form is expected after experimentation.
