Influences of user's posture and contact conditions of electrodes on the transmission characteristics of human body communication (HBC) were studied. A subject wore a transmitter on the left wrist and touched the receiver electrode with his right or left index finger. User's postures were selected from possible scenarios in practical applications. Electrodes of the transmitter and/or the receiver...
Ground loop through the floor is often modeled in the transmission model of Human Body Communication (HBC). This paper reports evaluation of ground loop through the floor in HBC between two subjects shaking their hands, and HBC between a subject and a stationary receiver on the floor. Subjects wore a transmitter or a receiver on the wrist. Received signal strength was measured on carpet-covered aluminum...
This paper proposed an in-vehicle application of human body communication as a form of communication technology that allows stable and low-energy communication within the vehicle. We investigated the transmission characteristics and electric field distribution between a wearable device attached to the driver's forearm and a transmitter mounted on the steering wheel. It was found that at a distance...
Intra-body communication draws attention as a promising wireless technology in order to materialize wireless body-centric networks. An electrode in intra-body communication system is a key device since the electrodes are analogous to antennas in airborne wireless communication system. However, nobody has addressed the broadband input impedance characteristics of the electrodes although there are a...
Human body communication is expected as a new human interface for communications among several persons. Thus, it is necessary to analyze the transmission characteristics between human bodies. In this paper, we compared the transmission characteristics between transmitter and receiver in the viewpoint of contact situation between two bodies. Moreover, the effect of receiver position on transmission...
