Passive Sensors Using RF Backscatter

An application of RF backscatter to monitor passive (zero DC power) sensors is presented. The technique uses an RF signal, from a probing platform, to probe a passive sensor. The passive sensor contains a transducer that acts like an impedance to RF si...
Low power wireless sensors are receiving considerable attention due to their multiple applications in the commercial and military scenarios. Wireless networks of “power aware” smart sensors are being developed that are deployed and forgotten, 1 as well as the sensor elements themselves. Transducers integrated with radio transceivers and networking...
