  • Method for producing a sensor element by means of laser structuring
    Patent number: 10378989
    Abstract: In order to produce accurate sensor element in a simple way, the invention provides a method for producing a sensor element (10) for a pressure or force sensor. Steps include, providing a component (13) to be deformed. Applying to the component (13), a sensor function and contact layer (24) 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 (24) by means of a laser, in such a manner that strain gauges (44) with a resistance structure with a meandering shape and contact pads (46.1, 46.2, 46.3, 46.4) remain standing.
