Method of production of an element sensitive to a stress, a device for converting a mechanical movement in the electrical signals and the transducer

摘要

The invention relates to a transducer electromecanique and its method of manufacture. / p & & p & this transducer uses a piezo - resistive or gauge element 12, the crystallinity is the same as that of the substrate 24 on which it rests. The element piezo - resistive is a gauge comprising two extreme portions 14, 16, connected by a collar which passes the - the top of a groove 25 provided in the substrate 14. The method of manufacture of this transducer 10 is such that the volume of material under stress can be lowered to a value of approximately 310cm. p / p field of application: measurement of forces and movements mechanical, etc..
