Abstract
The product comprises a sensor ( ) via which a measured quantity that corresponds to reactive resistance can be furnished within a measuring range. The product also comprises a matching network ( ) and a surface wave element ( ). The sensor ( ) is connected to a first reflector ( ) of the surface wave element ( ) via the matching network ( ). The first reflector ( ) forms, together with the matching network ( ) and the sensor ( ), a resonator which, for a value of the measured quantity within the measuring range, has a resonance with regard to a reflection of an acoustic surface wave on the first reflector ( ). The invention also relates to a method for determining the measured quantity and to a corresponding system.
