Bio-Optical Communication: A case-study of Out-to-In Body Interface

Internet of bio nano things (IoBNT) is a recent concept which foresees the possibility to interconnect biological or artificial nano devices to the Internet. This would enable the inner part of the human body as part of the global network. One of the major challenge to provide this inter-connectivity is how to move the information from outside to inside the body. This paper proposes a bio-optical communication (BOC) as a potential solution. The paper proposes to use a visible light communication (VLC) LED-based lamp to send a message to the human brain using the eye retina as a relay node. In fact, the eye and the brain can be seen as a natural VLC receiver. We aim to demonstrate that a VLC signal with specific configuration parameters (frequency, etc.) can be successfully demodulated at the brain level and to provide analytically the channel capacity of the communication link.
