The sensor includes a sensing circuit, a modulator connected to the sensing circuit and configured to modulate an input signal using variations in input impedance produced by the sensing circuit to produce a modulated output signal, and a transmitting element such as an antenna to transmit the modulated output signal to a receiver. In some implementations, the sensor includes a pilot sequence generator that may be powered by a received signal from a transmitting node. The input signal is thus modulated by both pilot data and the input impedance. The input signal may be received from the transmitting node. Alternatively, a power source may be provided in the wireless sensor for generating the input signal and/or pilot data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods for wireless/RFID sensors","description":"A wireless sensor is provided for use in near-to-zero or zero-power consumption applications.
