    With the continued miniaturization of unit computing, in foreseeable future, humans will be immersed in connected sensing and computing devices that form a complex distributed network connected to the cloud. Like the devices itself, humans are integral part of such networks designed to improve quality of human lives. The number of wearable devices are expected to grow to 600 million by 2020. These wearable/implanted devices present in, on and around the human body forms a complex network of sensor, actuation, computation, storage, communication and energy nodes on a human body, namely the Internet of Body (IoB).  IoB devices are typically interconnected using wireless body area network (WBAN) that suffers from connectivity bottleneck due to (1) high energy-cost of WBAN connectivity and (2) large data traffic through energy-sparse size-constrained devices. This talk will highlight how (1) Human Body Communication (HBC) provides an alternate energy-efficient and secure communication medium between wearable/implantable devices by using the human body as a conducting medium and provide order of magnitude improvement in physical security (as the critical information is contained within the human body and cannot be snooped on unless the person is physically touched) and energy-efficiency (due to low loss and broadband electrical conduction properties of human body). The science of signal propagation through human body will be explained using unifying BioPhysical models, followed by custom integrated circuit design that leverages the understanding to achieve >100x better energy-efficiency, compared to WBAN. (2) The edge-nodes will generate high data traffic leading to low battery-lifetime and increased network congestion. We will highlight how Context-aware Edge-analytics in IoB promises significant reduction in data-traffic without much loss of information content. This talk will conclude by highlighting how the combined benefit of HBC and Edge-analytics has the potential to transform Healthcare, Human Computer Interaction (HCI) and Neuroscience using IoB.
