  Intrabody communication (IBC), is a promising technology that can be utilized
for data transmission across the human body. In this study, a galvanic coupled
(GC)-based IBC channel has been investigated for implantable configuration both
theoretically and experimentally in the frequency range of 0 to 2.5 MHz.
Theoretical studies were performed by using finite element method (FEM) based
simulation software, called Comsol Multiphysics. A cylindrical human arm was
modeled with realistic values. Experimental studies were carried out with
chicken breast tissue as a substitute for human tissue. The pseudorandom noise
(PN) sequences were transmitted to investigate the correlative channel sounder
of tissue model. Results showed that the frequency affects signal propagation
through the tissue model. Additionally, it is crucial to cancel common-mode
noise in the IBC channel to enhance communication quality.
