Ambient backscatter communication enables passive sensors to convey sensing data on ambient RF signals in the air at ultralow power consumption. To extract data bits from such signals, threshold-based decoding has generally been considered, but suffers against Wi-Fi signals due to severe fluctuation of OFDM signals. In…

— Despite significant research in backscatter communication over the past decade, key technical open problems remain under-explored. Here, we first systematically lay out the design space for backscatter networking and identify applications that make backscatter an attractive communication primitive. We then identify…

'Joshua R. Smith'] Abstract – We introduce inter-technology backscatter, a novel approach that transforms wireless transmissions fro m one technology to another, on the air. Specifically, we show for the first time that Bluetooth transmissions can be used to create Wi-Fi and ZigBee-compatible signals using backscat ter…

Traditionally, active implants are powered by batteries, which, when discharged, have to be either replaced or recharged by an inductive power link. In the recent years, ultrasonic power links are also being investigated, as they promise more available power for deeply implanted miniaturized devices. Such devices often…

Ultrasonic acoustic power transfer is an efficient mechanism for coupling energy to millimeter and sub-millimeter implants in the body. To date, published ultrasonically powered implants have been encapsulated with thin film polymers that are susceptible to well-documented failure modes in vivo, including water…
