Abstract

In order to produce accurate sensor element in a simple way, the invention provides a method for producing a sensor element () for a pressure or force sensor. Steps include, providing a component () to be deformed. Applying to the component (), a sensor function and contact layer () consisting of a material with a k-factor between 2 and 10. Performing planar ablation of the material of the sensor function and contact layer () by means of a laser, in such a manner that strain gauges () with a resistance structure with a meandering shape and contact pads () remain standing.
