Abstract (en)

[origin: WO02089228A2] The invention relates to a composite material (5) comprising a first and a second constituent (11, 12) that are interconnected with material fit. The first constituent (11) behaves like a piezoelectric material, and the second constituent (12) behaves like a magnetoelastic material. The composite material is especially well-suited for use in a sensor element or in an actuator element, for example, a rotational-speed sensor, current sensor, torque sensor, force sensor or a passive sensor element. The invention also relates to methods for producing the composite material. A first method involves the compaction and sintering of a powder mixture, which consists of a first powder containing the first constituent (11) and of a second powder containing the second constituent (12). A second method involves the application of a coating containing one of the two constituents (11, 12) onto nanoscalar powder particles containing the other respective constituent (11, 12). A third method involves the creation of a layer (13, 14) containing one of both constituents (11) by sputter deposition or vapor deposition on a substrate, and a layer (13, 14) containing the other respective constituent is subsequently applied to this layer (13, 14).
