Data transmission system using a human body as a signal transmission path
Touch-responsive data transmission system for elongating transceiver battery life and assuring one-touch data transmission includes a first transceiver worn on user and a second transceiver connected to equipment utilizing first transceiver data. User contacts first transceiver signal and ground electrodes and touches a second transceiver touch electrode to establish a signal path through user. First transceiver includes a detector for detecting a start signal from the second transceiver signal electrode. Second transceiver includes a generator for generating the start signal upon touching the touch electrode. Receiving the start signal, circuit elements responsible for data transmission are battery-energized to start data transmission from first to second transceivers. Circuit elements responsible for transmitting data remain deenergized until user touches the second transceiver touch electrode to save energy during non-operation and prolong first transceiver battery life. By touching the touch electrode, automatic data transmission remains possible without requiring additional starting procedures.
