Abstract

Le dispositif comprend: une structure de support (2) destinée à etre fixée au corps (1) dont l'accélération ou les vibrations doivent etre mesurées, et comportant un substrat (2) qui est déformable élastiquement sous l'effet d'une accélération du corps (1); au moins une résistance en couche épaisse (3) étant appliquée au substrat (2) de telle sorte que lors de l'utilisation, elle subisse des déformations correspondant de manière univoque aux déformations du substrat (2), et des moyens de circuit (8) connectés à la résistance au moins (3) et agencés de manière à produire des signaux électriques indiquant les variations de sa valeur de résistance.The device comprises: a support structure (2) intended to be fixed to the body (1) whose acceleration or vibrations must be measured, and comprising a substrate (2) which is elastically deformable under the effect of an acceleration body (1); at least one thick film resistor (3) being applied to the substrate (2) so that during use, it undergoes deformations unequivocally corresponding to the deformations of the substrate (2), and circuit means (8 ) connected to the resistance at least (3) and arranged so as to produce electrical signals indicating the variations in its resistance value.
