The developmental history and fields of application of magnetostrictive materials are presented. The various characteristics of the materials are compared with that of piezoelectric(PZT) material P b(Zr, Ti)O 3. Some research works on ultraprecise micromoving actuator and optic fiber magnetoelastic sensor in Wuhan University of Technology are reported. The application situation of the materials in the future is also discussed.
