Abstract:Health care is getting a lot of attention. Especially due to population aging, health care has to be made affordable in the future. There is a need for enabling in-body communication and also localization of sensors which are moving through the human body. The propagation of radio frequency signals through different layers of human tissue is analyzed. In contrast to other research the complex characteristics of human tissue are included for both received signal strength and time of arrival methods. A multilayer model is developed to investigate the influences of different tissue layers on the absolute signal attenuation and travel time for signal propagation from in-body to on-body for in-body communication allocated frequencies: 403.5 MHz, 916.5 MHz, and 2.45 GHz. The analysis results show that the attenuation and delay in small intestine and muscle tissues have more influence on the total values than in fat tissue.
