Human body position estimation system using electric field resonance coupling

Today in terms of security and caring, more various and robust information system about human existence in indoor environment (ex. rooms, buildings) are needed. Especially, human position estimation system in such kinds of spaces is basic. Generally, such kind of systems use radiowave devices, cameras and ultrasonic devices to estimate human position. But these kind of systems have some weakpoint when the system tries to estimate position. A purpose of this paper is to propose novel human position estimating system using electric field resonance coupling and validate the evidence for possibility of human position sensing system using resonance coupling by simulation experiment. In simulation experiment results using Gabriel´s human phantom, relation between electric field strength and distance between sensor and human are confirmed. In conclusion, feasibility of the proposed human position estimation system is shown.
