Abstract

A biological signal detection system includes a pair of electrodes, adapted to be attached on a living body; a transmitter, adapted to be attached on the living body, and including an electric circuit operable to process the biological signal and to telemeter the processed signal; and a biological signal inputting apparatus. The system may also include a receiver-transmitter operable to receive the processed signal telemetered from the transmitter and to telemeter the processed signal to the biological signal inputting apparatus by way of a wide area network; and a storage for storing the processed signal telemetered from the transmitter as biological signal data and for inputting the biological signal data to the biological signal inputting apparatus. Also, the system may include a storage for storing the processed signal telemetered from the transmitter as biological signal data and for inputting the biological signal data to the biological signal inputting apparatus.
