In-vivo sensing, diagnosis and treatment of diseases is having a great attention lately. With advanced computational systems, the processing of the biological data as well as the prediction of diagnosis is becoming more promising. However, the implementation of these systems inside the human body has a major challenge: modeling the communication channel. To overcome this problem, researchers are investigating the main factors that define the characteristics of the communication channel between nano-devices. In this work, we summarize the elements that contribute to the path loss encountered by an EM wave in-vivo. The spreading of propagating wave, the molecular absorption from the biological tissue and the scattering from the body particles are discussed. Keywords—Absorption; path loss; scattering; nano-devices.
