Abstract

A magnetoelastic sensor (1) for detecting static and dynamic micro-deformations is described and comprises a magnetoelastic ferroomagnetic element (11), an excitation coil (6) for sending an excitation signal to the ferromagnetic element (11), and a detection coil (7) for detecting a first signal emitted by the ferromagnetic element (11) as a consequence of the excitation signal. A sensor of this type is improved by the provision of a permanent magnet element (21) to be connected firmly to a body, the static and dynamic deformations of which are to be measured. A sensor of this type is also improved by the provision of a sheathing (12) of resilient material for the ferromagnetic element (11), fitted in a manner such that the ferromagnetic element (11) is at least partially embedded in the sheathing (12). A method of measuring static and dynamic micro-deformations is also described.
