Influence of nearby objects and body motion on body-centric wireless communications

Recently, body-centric wireless communications have become a very active area of research because of many attractive applications. In reality, nearby objects and body movement will more or less impact the system performance and such influence will depend strongly on the frequency used. This paper describes the influence of nearby objects on the electric field distribution around the human body over a wide frequency range from 3 MHz to 3 GHz and body movement (walking) on received open voltages at an ankle and a wrist. The results show that the influence was relatively small for lower frequency range like below 30 MHz.
