Title:
MULTILAYER MAGNETOSTRICTIVE TRANSDUCER AND MAGNETOSTRICTIVE COMPOSITE MATERIAL FOR SAME
Document Type and Number:
WIPO Patent Application WO1999015281
Kind Code:
A8
Abstract:
A multilayer magnetorestrictive transducer (29) comprising a first layer (32) made at least partially of a magnetic material and a second layer (37) made at least partially of a magnetorestrictive material disposed on the first layer (32). The first layer (32) magnetically biases the magnetorestrictive material of the second layer (37). The transducer (29) includes a magnetic field generator (41) for producing a magnetic field that extends through at least a portion of the second layer (37) to change the shape of the second layer (37) and thus exert a force on the first layer (32).
