ABSTRACT:
The invention relates to a strain-sensitive resistor, comprising a resistance layer arranged on a support element and an electromechanical transducer produced with this resistor.An increase in the electrical measured signal picked off across the resistor is achieved in a simple way by the support element (1) having a recess (7) on its surface (9) which, when the support element (1) is subjected to mechanical stress in at least one area of the surface (9) of the support element (1) in which the resistance layer (4) is positioned, produces a ratio between the two main strain directions (L, T) of the resistance layer (4) which differs in magnitude.
