Abstract

An electrode 4 for detecting a biological signal and a loop antenna 3 are integrally mounted on a support 2 placed on the surface of a living body and a transmitter 5 is placed on the support 2. A biological signal detected on the electrode 4 is input through a connector 11 to electric circuitry 10 of the transmitter 5 and an electric signal processed by the electric circuitry 10 is output through connectors 12 and 13 to both ends of the loop antenna 3 from which the biological signal is emitted to a receiver. At this time, the opening face of the loop antenna 3 is in a direction almost perpendicular to the surface of a living body for improving sensitivity.

Claims

1-17. -17. (canceled)

18. A biological signal detection system comprising:

a first electrode group for detecting a biological signal;

a first support, attached to the living tissue, for supporting said first electrode group;

a second electrode group for detecting a biological signal;

a second support, attached to the living tissue surface, for supporting said second electrode group; and

a transmitter including;

an electric circuit for processing the signals detected by said first and second electrode groups;

a first connection section for electrically connecting said first electrode group to said transmitter and fixing said transmitter directly onto said first support and a second connection section for electrically connecting signal lines from said second electrode group to said transmitter;

storage means for storing the signals processed by said electric circuit;

an external transmission signal comprising instructions; and

a first transmitter-receiver for telemetering the signals processed by said electric circuit and the signals stored in said storage means and receiving an external transmission signal, said transmitter-receiver telemeters some or all of the signals stored in said storage means or the signal processed by said electric circuit based on said instructions received from said external transmission signal.
