“…We [6,7,8] have shown that the optimal configuration is composed by transmission and receiver electrodes without ground electrodes and a diameter of 2cm because of the lowest attenuation performed. From a point of view of time delay, the configuration of transmission and receiver electrodes without ground electrodes does not provide the best performance.…”

Ubiquitous communication seems to be in practical use these days. However we are still looking for a new promising communication infrastructure for personal area network. In this paper, we show some of the body area communication characteristics and applications for the future personal area application. We have investigated both of the Intra-Body communication and Inter-Body communication in terms of propagation and application respectively. Various kinds of wearable devices have been developed for many purposes. Some of the medical applications require very small size of the transmission device in order to have enough portability and long life time. Body area communication seems to give us the answer such requirement.

“…The secondary electric field is radiated from the charge induced on the entire surface of the human body (7). When a human body with a secondary field radiation touches the top of the electrodes embedded in the floor (8), electrostatic induction occurs on top of these electrodes (9). As a result, potential is generated between the receiving electrodes (10).…”

“…There are various methods of near-field intrabody communication; [1][2][3][4][5][6][7][8][9][10][11][12][13][14] however, to realize communication at a high data transfer rate, the use of a communication system with a quasi-electrostatic field (an electric field) as the communication transmission carrier is promising.…”

In this paper, we describe how to obtain a low cost electrooptic (EO) sensor module for the mass production of nearfield intrabody communication devices. In our previous study, we used a bulk cleavage technique to fabricate EO modulators without the need for any optical polishing or washing processes. In this study, we fabricated EO modulators as a miniaturized chip sensor without a base portion, and clarified the feasibility of assembling optical components by only a passive alignment technique with a compact housing. #

“…Therefore, the antenna is one of the key elements in the wireless body area networks. Antennas with omni-directional radiation [9]- [11] in free space and diversity [12]- [16] are commonly used in body area networks However, the radiation patterns will be altered when the antennas are placed near the body. Therefore, by using antennas of different radiation characteristics, the overall system performance can be optimized.…”

Abstract-An experimental study on the use of ultra-wideband antenna systems (3.5-4.5 GHz) on the human body for wireless body area network (WBAN) applications is conducted. It has been found that the link reliability can be improved and transmit power can be reduced by properly selecting the transmit and receive antennas with different radiation properties (omni-directional, directional, pattern diversity) and polarizations (vertical and horizontal) at each location on the body. Moreover, when there is blockage by the body, it may be possible to achieve better transmission when the antennas are horizontally polarized. Also, antennas with pattern diversity can be used to enhance the overall reliability of the communication system. In order to eliminate the use of cables in the measurements, an on-body UWB system has been developed and the reliability can be assessed more practically in terms of the peak amplitude of the received waveform and the bit error rate. It has been observed that when the link quality is improved, the transmit power can be reduced by more than 20 dB without compromising on the reliability, which will conserve the battery power.Index Terms-Antennas, bit error rate, diversity, propagation measurements, RF transmission, ultrawide band, wireless body area network.
