Abstract :
This paper describes a hybrid device that comprises of both a magnetostrictive rod and an amorphous wire magnetic sensor that could be used for force sensing applications. The amorphous sensor uses a frequency modulation technique to detect changes in the wire´s permeability. These permeability changes were a result of stress-induced changes in magnetization in a dynamically compressed magnetostrictive rod that was in close proximity to the amorphous sensor
