Abstract:
1. A sensor arrangement remotely readable by a separate reader utilizing radio frequencies for determining desired quantities from sources, the arrangement comprising: an LC resonator comprising a capacitor and a coil, an electrically conductive ring, a sensor element coupled to the LC resonator, whose properties change as a function of a measurable quantity, the sensor element being coupled inductively with the LC resonator without forming a direct galvanic contact, wherein the sensor element is arranged inside the electrically conductive ring and is thinner than the electrically conductive ring, and a package containing foodstuffs or medicinal substances, wherein the sensor element is arranged inside the package and the coil is arranged outside the package, wherein the coil is configured to generate a magnetic field on a location of the sensor element, and wherein the sensor element directly affects the magnetic field generated by the coil.
