    Abstract:

    The Intra-Body Communication (IBC) based on optoelectronic modulation is believed as an available method to achieve high speed and reliable signal transmission based on human body channel. In this paper, the sensitivity characteristics of the Electrostatic Coupling IBC based on Mach-Zehnder (M-Z) electro-optic modulation have been investigated. Firstly, the mathematic model of the Electrostatic Coupling IBC based on M-Z optoelectronic modulator has been proposed, while the sensitivity characteristics of this kind of IBC are discussed. Secondly, the corresponding measurements were carried out to verify the proposed model. Our investigation indicates that the simulation results of the sensitivity characteristic coincide with the corresponding in vivo measurement results, while the proposed model will help to achieve reliable, high speed and low cost intra-body communication.

    Abstract:

    Intra-body Body Communication (IBC) is a communication technology in which human body is used as a signal transmission medium.

Finally, some important conclusions are deduced on the basis of simulation results.

  • evaluation and verification of channel transmission characteristics of human body for optimizing data transmission rate in Electrostatic Coupling intra body communication system a comparative analysis
    PLOS ONE, 2016

    Abstract:

    Background Intra-body communication is a new wireless scheme for transmitting signals through the human body. Understanding the transmission characteristics of the human body is therefore becoming increasingly important. Electrostatic-Coupling intra-body communication system in a ground-free situation that integrate electronic products that are discretely located on individuals, such as mobile phones, PDAs, wearable computers, and biomedical sensors, are of particular interest. Materials and Methods The human body is modeled as a simplified Resistor-Capacitor network. A virtual ground between the transmitter and receiver in the system is represented by a resister-capacitor network. Value of its resistance and capacitance are determined from a system perspective. The system is characterized by using a mathematical unit step function in digital baseband transmission scheme with and without Manchester code. As a result, the signal-to-noise and to-intersymbol-interference ratios are improved by manipulating the load resistor. The data transmission rate of the system is optimized. A battery-powered transmitter and receiver are developed to validate the proposal. Results A ground-free system fade signal energy especially for a low-frequency signal limited system transmission rate. The system transmission rate is maximized by simply manipulating the load resistor. Experimental results demonstrate that for a load resistance of 10k−50k Ω, the high-pass 3 dB frequency of the band-pass channel is 400kHz−2MHz in the worst-case scenario. The system allows a Manchester-coded baseband signal to be transmitted at speeds of up to 20M bit per second with signal-to-noise and signal-to-intersymbol-interference ratio of more than 10 dB. Conclusion The human body can function as a high speed transmission medium with a data transmission rate of 20Mbps in an Electrostatic-Coupling intra-body communication system. Therefore, a wideband signal can be transmitted directly through the human body with a good signal-to-noise quality of 10 dB if the high-pass 3 dB frequency is suitably selected.
