HUMAN BODY COMMUNICATION APPARATUS

摘要

There is provided a human body communication apparatus capable of performing communications through the contact with external devices (a central processing unit) and a human body. The human body communication apparatus includes a plurality of contact sensor units including a plurality of electrode contacted with a human body and having conductivity, and a plurality of electrostatic sensor units coupled to the electrodes to sense an electrostatic capacity changed through the contact with the human body and generate a contact signal using the sensed electrostatic capacity; a signal analyzer unit for analyzing the contact signal received from the contact sensor units; and a control signal generator unit for generating a control signal as the analysis result in the signal analyzer unit. Therefore, the human body communication apparatus may be useful to minimize the power consumption of modem for human body communication or transceiver circuits by recognizing predetermined patterns of the user so as to reduce the unnecessary power consumption when the communication input/output apparatus, particularly a mobile device, using a human body as a medium is in contact with the device for the purpose of other uses other than the human body communications, and to minimize the power consumption to extend the standby time of the mobile devices.
