Radiofrequency based sensor arrangement and a method |
摘要 |
A sensor arrangement for a sensor arrangement remotely readable by radio frequencies. The sensor arrangement includes an LC resonator that includes a capacitor and a coil, and a sensor element coupled to the LC resonator whose properties change as a function of a measurable quantity. A sensor element according to the invention does not form a direct galvanic contact with the LC resonator, rather the coupling is implemented capacitively or inductively.
