Breaking Barriers in-Vivo THz Communication Analysis for Nano Networks in Human Tissues

Abstract

Body Nano-Communication based on RF radio communication in the terahertz band supports health and fitness industry applications. Nano communications primary facilitate real-time monitoring of biological and chemical substances inside the human body, helping an early detection of stroke and heart attack risks. Monitoring small communication range inside the human body via electromagnetic propagation is not an easy task; thus, in this paper, we investigate the path loss of radio propagation in three human tissues: blood, skin, and fat using a Tera-Hertz frequency range in between 0.5 and 1.5 THz. The results support the idea that the path loss inside the human body depends on the dielectric loss of human tissues and the function of frequency and distance. It also shows that increasing the distance and the frequency of the signal inside the tissues, such as blood, fat, and skin, the path loss increases because the attenuation increases when the frequency increases. Furthermore, the study examines the effect of Doppler as a method of measuring the speed of blood flow to predict the early risks being considered.
