Wakeup receiver design for low power consumption based on HBC

HBC is widely used than the traditional radio frequency (RF) communication, which has multiple advantage due to modulating the electric field induced to a human body, it is possible to transfer data wirelessly using the body as a transmission medium. First, reducing the traffic load from the radio channels becoming more congested as no of connected wireless devices increases rapidly. Second, HBC can potentially provide higher security than RF communication since the electric field stays closer to human body, which makes eavesdropping more challenging. Third, the attenuation in the HBC frequency band is lower than radio technologies for wireless body area networks. To improve energy efficiency in HBC by utilize a wake-up receiver. The WUR is continuously listening for a pre-defined wake-up signal, which activates other electric circuitry (e.g., sensing, processing, and communication). The use of WURs can significantly reduce the energy consumption and increase the lifetime of the sensing applications.
