The tag comprises an antenna to couple to an RF field of the tag reader and first and second resonant circuits, the first comprising a non-linear, adaptive resonator configured to automatically self-tune to a frequency of the RF field, the second a linear resonator. The tag also has a local power store. The tag powers up using the non-linear, adaptive resonator, which can automatically self-tune without an external power supply, and this resonator is used to charge the local power store. Once operational the tag switches to using a linear resonator for communicating with the tag reader."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID tags","description":"An RF tag for sending data to a tag reader is described.
