Abstract :
This paper introduces a new method for in-vivo determination of the dielectric properties for embedded regions in human tissues. A surgery-free method is proposed for on-body monitoring system to evaluate the dielectric properties of internal body components (lung, heart etc) and to effectively determine irregularities in real-time. The method uses a set of electrodes at low frequencies (10MHz) to obtain data that can determine the underlying layered structure. By using multiple electrodes, the effects of outer layers (skin, fat and muscle), are suppressed allowing for the characterization of deeper dielectric layer. In this paper, we present a proof of concept based on simulations. experimental data will be presented at the conference.
