Abstract:
1. A pressure sensor device comprising: a substrate comprising an electrical insulation material, said substrate further comprising a first reservoir, a second reservoir in communication with the first reservoir and of which two internal walls are each equipped with an electrode; a flexible membrane comprising an electrical insulation material, said flexible membrane comprising a protuberance and secured to the substrate so as to enable movement of the protuberance between a position in which it is at a distance from a liquid filling the first reservoir and at least one second position in which it exerts a pressure on the liquid, thus discharging it at least partially from the first reservoir toward the second reservoir with mechanical contact with the two electrodes, said mechanical contact of the liquid with the two electrodes establishing a resistance or capacitance between the two electrodes.
