Abstract: Intra body communication has been researched quite extensively for past couple of decades to serve the needs in real time monitoring, drug delivery, sensing for pre-emptive measures and to provide better quality of living to the population. The applications are not just limited to health care but also span the areas of recreation, sports and information technology. A handful of intra body, more specifically human body centric (HBC) communication modalities have been developed so far namely galvanic, capacitive and inductive methods. Human body or part is used as a communication channel in these technologies. Though they offer the possibility to connect devices and transfer data wirelessly from one part of the body to the other they suffer from one common drawback which is the low bandwidth hence lower data rates. Radio frequency communication has been regarded until recently as an improbable candidate for extensive HBC applications.

In 2016 Asan et. al from the Microwaves in Medical Engineering Group, Uppsala University, Sweden published her first paper on the feasibility using the adipose tissue to transmit Microwave signals inside the body with significantly low loss(2dB/cm). Since then a number of articles have been published on different aspects of fat – intra-body communication (Fat-IBC). Considering the human anatomy the fat tissue is found to be sandwiched between denser tissues such as skin and muscle. As it is known that the fat due to its very low water content has low permittivity and losses while muscle and skin do have almost an order of magnitude high permittivity and losses which is three to four times that of fat. This creates a natural wave guiding structure which we can utilize to transmit microwave signals at ISM frequencies. Fat- IBC pushes further the current limits in intra-body data transfer by providing a higher bandwidth and enabling better power management to ensure longer implanted battery life. Fat channel communication will also help substantially the development of artificial limbs which require transfer of high volume electrophysiological data, wirelessly. 

Bio: Prof. Robin Augustine graduated in Electronics Science from Mahatma Gandhi University, India in 2003. He received a Master's degree in Electronics with Robotics from Cochin University of Science and Technology, India in 2005, and a Doctoral degree in Electronics and Optic Systems from Univerisité Paris Est Marne La Vallée, France in July 2009. He served as Post Doctoral researcher at University of Rennes, France from 2009-2011 and joined Uppsala University as a senior researcher in 2011, before becoming associate professor in 2016. He is now a Senior University Lecturer in Medical Engineering and Docent in Microwave Technology. He is the head of The Microwaves in Medical Engineering group and current research includes the fields of wearable antennas, BMD Sensors, microwave phantoms, dielectric characterization, Bionics, mechatronics, Non-invasive Diagnostics, point of care sensors for physiological monitoring, clinical trials, animal trials, in and on body microwave communication. He has pioneered the Fat – Intra Body Communication technique.
