Claim 24:
25. The device according to claim 24, wherein a second sensor, comprising a second piezoresistive element essentially identical to the piezoresistive element, is provided whose sensor measurement variable is the electrical resistance of the second piezoresistive element,
in that a voltage divider is provided to generate the first phase-shifted comparison signal, wherein the voltage divider is formed from a first electrical resistance and a second electrical resistance and wherein the second electrical resistance includes the electrical resistance of the second piezoresistive element,
in that a further voltage divider is provided, which is formed from a third electrical resistance and a fourth electrical resistance to generate a second phase-shifted comparison signal by the further voltage divider,
wherein the voltage divider and the further voltage divider are part of a bridge circuit.
