The first and the second branch have a terminal in common. The first branch comprises a first node between said the current source and the first stimulus responsive sense element configured to generate a first signal related to a voltage over the first sense element. The second branch comprises a second node between the second current source and the second stimulus responsive sense element configured to generate a second signal related to a voltage over the second sense element.
A piezo-resistor-based sensor, and a method to fabricate such sensor, comprise a sensor having at least a sensing element provided on a flexible structure, such as a membrane or cantilever or the like. The sensing element includes at least one piezo-resistor comprising at least a first region of the flexible structure doped with dopant atoms of a first type. The flexible structure furthermore comprises a second doped region within it, at least partially overlapping the first doped region, forming a shield for shielding the sensing element from external electrical field interference, wherein dopant atoms of the second doped region are of a second type opposite to the dopant atoms of the first doped region, for generating a charge depletion layer within the flexible structure at the overlapping region between the first doped region and the second doped region.

The invention relates to sensors comprising a substrate, a platinum component having a first surface facing toward the substrate and a second surface facing away from the substrate, a protective covering over the platinum component, the protective covering comprising one or more layers, at least on of which is an oxygen getter material, a lower surface in physical contact with the second surface of the platinum component, and an upper surface; and a method for forming such a sensor. The protective covering with oxygen getter material protects the platinum component against oxygen dissolution therein, thereby reducing sensor drift.
