Bio-signal apparatus, operation method of bio-signal apparatus and manufacturing method of bio-signal apparatus

A bio-signal apparatus, comprising:

• a first connection part, a second connection part and a seal;
• wherein:
• the first connection part comprises a sheet;
• the sheet is configured to carry a patch electrode structure, which comprises electrodes configured to receive a bio-signal from a body of a mammal and first electrical connectors, the first electrical connectors being electrically connected with the electrodes;
• the second connection part comprises counterpart electrical connectors, the first electrical connectors and the counterpart electrical connectors being repeatedly attachable and releasable with each other to transfer the bio-signal therethrough to data processing;
• the seal is configured to seal an interface of the first connection part and the second connection part against dust and moisture, and the seal is configured to surround the first electrical connectors and the electrical counterpart electrical connectors in a continuous manner;
• and
• the second connection part comprises a physical connecting mechanism and second electrical connectors electrically coupled with the counterpart electrical connectors, and the bio-signal apparatus comprises a bio-signal receiver, which comprises receiver electrical connectors, which are counter-connectors to the second electrical connectors, and the second electrical connectors and the receiver electrical connectors are configured to transfer the bio-signal to an electric circuit of the bio-signal receiver to store the bio-signal in at least one memory of the bio-signal receiver.
