Paper Abstract

Magnetoelastic sensors, made of amorphous metallic glass ribbons or wires, have been used to measure various environmental parameters such as temperature, humidity, viscosity, and chemical concentration including pH, carbon dioxide, and ammonia. The parameter of interest is determined by remote detection of the shift in the resonant frequency of the magnetoelastic sensors, which is dependent upon several factors including stress, pressure, temperature, and magnetic field. This paper describes the operating principles of the magnetoelastic sensors and presents several proven applications, as well as methods for optimizing the sensor performance.
