Definitions

  • the invention aims to solve the drawbacks of the prior art and for this purpose concerns a pressure or force sensor, able to produce a sensitivity compensation to the environment, especially to temperature, and comprising:
  • the touch screen (800) implements a series of compensated sensors using two single-layer elementary sensors (100, 100 ') and two multilayer elementary sensors (200, 200'), all related to the same face of the substrate and mounted as a complete bridge.
  • the use of a complete bridge makes it possible in particular to further improve the linearity of the response, and to increase the sensitivity of the sensor with regard to the half-way fitting. bridge.
