Abstract :
A magnetostrictive force sensor was presented, which was based on the piezomagnetic effect. Relation between magnetic flux density in the gap and applied stress on the magnetostrictive force sensor was computed by the finite element method and measured. It is found that the computed result trendency is similar with the measured one. It has been proved that the giant magnetostrictive material is suitable for use in force sensor and the structural design of force sensor is valid. The effects of various factors on performance of force sensor were also analyzed
