A plurality of wearable devices have appeared recently. The requirements of communication method for wearable applications are wearing comfort, easy use with intuitiveness and low power consumption. In this paper, 10Mbps human body communication method which has extremely low power consumption is presented. The differences between HBC in IEEE 802.15.6 and proposed 10Mbps HBC, SoC architecture and implementation, performance of evaluation board and application are discussed.

Human body communications (HBC), which have been standardized in IEEE 802.15.6 standard for wireless body area networks (WBAN), provides a maximum data rate of 1.3125 Mbps through frequency selective digital transmission (FSDT). This paper reviews FSDT and proposes a modified FSDT (MFSDT). By exploiting the efficient modification of the FSDT's transmitter structure, MFSDT achieves a maximum data rate of 3.9375 Mbps, and the decoding complexity of MFSDT increases linearly with an increase in the data rate. In addition, FSDT and MFSDT performance are investigated with respect to the effects of the transmit filter provided to meet transmit spectral mask requirements, and a human body channel modeled as a finite impulse response filter.

An intuitive context aware service between two devices is possible using touch with the intrabody communication. Using this technology, users with multimedia devices may simply touch them to establish network connection, transfer data, and provide the required service; hence the name Touch-And-Play (TAP). Using TAP, users can disclose their context by touching the specific device. For instance, a user carrying a digital camera touches the TV to begin a slide show or a printer to print a photo. TAP is expected to enable the provision of intuitive, context-aware service. This paper discusses the feasibility of TAP and its application in user interface.

This paper presents a novel intrabody communication system, in which the base-band signal is directly transmitted through human body and electrically recovered, and its architecture are. The electrical characteristics of the human body in terms of a communicational channel are investigated from 1KHz to 10MHz using the equipment with a floating ground. The signal from universal asynchronous receiver transceiver (UART) port of microcontroller with 3V peak is used as the output of transmitter. The receiver board occupied 2.2 times 2.2cm2areas and consumes 30mW power with 3V supply voltage. The packet error rate (PER) of 10-8is obtained with a packet size of 77bits. The proposed system named Touch-And-Play (TAP) is implemented and validated by transferring the JPEG file with Manchester coded digital signal up to 1Mbps from one hand with a microcontroller to the opposite one with the functional equivalence of the printer through human body by touching them
