Abstract

A strain-sensitive resistor including a resistance layer arranged on a support element and an electromechanical transducer produced with this transistor. The support element has a recess in its surface. When the support element is subjected to mechanical stress in at least one area in which the resistance layer is positioned, the recess produces a ratio between the two main strain directions of the resistance layer which differs in magnitude.
