摘要： Provided is a communication apparatus having a human body contact sensing function and method. The apparatus includes: an electrode that comes in contact with the human body; a contact sensor coupled to the electrode that instructs the CPU to perform an initial operation if contact with the human body is sensed; and a data processing unit that receives a control signal from the CPU to select whether to transmit or receive data, and performs a transmitting or receiving operation according to the control signal. To reduce power consumption in a stand-by state before body contact is made when using a human body as a communication medium, a human body contact sensor is included to minimize power consumption of a micro processing unit and a transmitter/receiver circuit until contact occurs. Minimizing power consumption when in a stand-by mode by using a contact sensor with low power consumption extends stand-by time.
