Abstract
A device for determining a measurand, includes a first pattern made from a first conductive material, the first pattern having a first impedance and having a first end and a second end spaced apart from the first end, a second pattern at least arranged between the first end and the second end of the first pattern, being in electrical contact with the first pattern. The second pattern has a second impedance that changes continuously as a function of the measurand, such that the impedance or the inductance of the assembly formed by the first and second patterns changes continuously as a function of the measurand. The device also comprises a means for determining the impedance or the inductance of the assembly, formed by the first and second patterns.
