Abstract

It is shown that the amplitude of resonant magnetoelastic waves is very sensitive to local change of magnetic field. Since a moving object can be related to a variation of the magnetic field produced by its displacement, the last one is detected and its amount evaluated by means of a sensor based on magnetoelastic waves. The prototype of this type of sensor is presented and several experimental results are reported to prove the preceding asserts. (C) 1997 Elsevier Science S.A.
