Abstract

Un détecteur à jauge comprend un substrat de support (1) sous la forme d'une plaque faite de matière électriquement isolante, de préférence une matière céramique, sur une face de laquelle est déposée au moins une résistance à couche épaisse (R) , ledit substrat de support (1) étant destiné à etre fermement fixé par son autre face sur un organe ou une structure dont les efforts et déformations doivent etre détectés localement, de telle sorte que lesdits efforts ou déformations déterminent, par l'intermédiaire du substrat (1), des déformations correspondantes de ladite au moins une résistance à couche épaisse (R).
