Abstract:
A portable device for data communication using a body as a conductor to transmit data to a receiver, the portable device includes a data receiving unit to receive data, a controller unit to control processing of data to be transmitted, a current limiting circuit to limit a current of a signal corresponding to the data to be transmitted to a predetermined value, and transmitting electrodes connected to the current limiting circuit and to contact the body to transmit the signal having the current of predetermined value to the receiver.
Abstract:
The present invention provides a method and apparatus for receiving data in a human body communication system. The receiving apparatus, which comprises plural receiving electrodes, selects the optimum pair of receiving electrodes when receiving data, so that it can improve quality of received information and obtain position information of a sensor in the human body.

Abstract:
The present invention provides method and system for data communication in the human body and a sensor therefor. The method and system transmit information through the human body to a receiver located outside the human body using low current and voltage polarity, so that they cause no damage to the human body and achieve low power consumption and better receiving sensitivity. In addition, the sensor contains a CMOS image sensor on which all circuits are integrated without radio transmitter and antenna, so that it achieves a low-priced and small-sized capsule type endoscope.
