A dual-radio solution for wireless body area networks (WBANs) is proposed in this paper. Solution is based on the usage of wake-up receiver (WUR) and impulse radio ultra wideband (IR-UWB) technique. In the proposition, the data to the hub is transmitted using IR-UWB and the control messages back to a node are received using WUR. Energy efficiency model has been developed to compare proposed solution's...
The previous research works have shown that the modulation of the electric field induced on the human body surface enables to transfer data wirelessly. Method is known as human body communications (HBC) which has multiple advantages in comparison to traditional wireless radio communications over air. They include lower attenuation, less interference to/from other wireless devices, as well as the better...
A superregenerative wake-up receiver with addressing capability (SR-WUR) for medical and wireless body area networks (WBAN) is proposed in this paper. The SR-WUR is based on a self-quenched superregenerative oscillator (SRO) which enables high sensitivity while maintaining low power consumption. Due to the high sensitivity, low transmit power can be used, which reduces the energy radiation towards...
