Continuous multi-channel monitoring of biopotential signals is vital inunderstanding the body as a whole, facilitating accurate models and predictionsin neural research. The current state of the art in wireless technologies foruntethered biopotential recordings rely on radiative electromagnetic (EM)fields. In such transmissions, only a small fraction of this energy is receivedsince the EM fields are widely radiated resulting in lossy inefficient systems.Using the body as a communication medium (similar to a 'wire') allows for thecontainment of the energy within the body, yielding order(s) of magnitude lowerloss than radiative EM communication. In this work, we introduce Animal BodyCommunication (ABC), which utilizes the concept of using the body as a mediuminto the domain of chronic animal biopotential recording. This work, for thefirst time, develops the theory and models for animal body communicationcircuitry and channel loss. Using this theoretical model, a sub-inch$^3$,custom-designed sensor node is built using off the shelf components which iscapable of sensing and transmitting biopotential signals, through the body ofthe rat at significantly lower powers compared to traditional wirelesstransmissions. In-vivo experimental analysis proves that ABC successfullytransmits acquired electrocardiogram (EKG) signals through the body withcorrelation accuracy >99% when compared to traditional wireless communicationmodalities, with a 50x reduction in power consumption.
