Abstract :
This paper presents a method of using volume conduction for communication with implanted passive RFID devices. Generating mainly electric field through human tissue, this method can reduce the interference with metallic implants when RFID devices are attached to the implants. Exterior and interior electrodes are designed for efficient energy and signal transmission. Experiments with a saline box are conducted to study the signal attenuation through biological tissue and the feasibility of using volume conduction for RFID devices close to in vivo metallic materials.
