A scalable 2.9mW 1Mb/s eTextiles body area network transceiver with remotely powered sensors and bi-directional data communication
منشور في 2015"…Micropower sensors should also be powered by a non-local energy source for system miniaturization and long life. Recently proposed communication systems using wireless body area networks [1,2] and body-coupled communication [3] suffer from high path loss around the human body for efficient remote power delivery. …"
