10. A bio-signal measurement system, the bio-signal measurement system comprising:
a disposable patch electrode structure comprising:
a front flap and a main structure, which is configured to be attached to skin for a bio-signal measurement, the patch electrode structure being configured to feed electrical bio-signals to a non-disposable bio-signal device; wherein:
the front flap is separated from the main structure by a non-enclosing front flap cut, material of the front flap being thus formed as continuous material of the main structure;
a material connection of the continuous material between a rear section of the front flap at a non-enclosing side of the front flap cut and the main structure is configured to allow tilt of the front flap with respect to the main structure in response to rise of a frontal section of the front flap, the frontal section being opposite to the rear section;
the front flap is fully surrounded by the main structure; and
the front flap comprises contact electrodes at the frontal section, the contact electrodes being both connected with measurement electrodes of the main structure through conductors via the material connection and configured to connect with counter-electrodes of a connector separate from the patch electrode structure; and
a connector comprising:
a non-disposable base structure with a face and counter-electrodes on an outer surface next to the face, the base structure being configured to be slit on a main structure of a disposable patch electrode structure toward a front flap of the patch electrode structure with the face ahead, a frontal section of the front flap comprising contact electrodes, which are both connected with measurement electrodes of the patch electrode structure through conductors and configured to connect with the counter-electrodes separate from the patch electrode structure; wherein:
the face is configured to cause the frontal section of the front flap to rise in a tilting manner based on a material connection of continuous material between a rear section of the front flap and the main structure that is configured to allow the tilt of the front flap with respect to the main structure, the frontal section being opposite to the rear section;
the electrical device is configured to cause the counter-electrodes and the contact electrodes to approach each other in response to the slide of the electrical device toward a rear section of the front flap, where the contact electrodes and the counter-electrodes match together for an electrical contact; and
the face is further configured to enter a predetermined gap matched for the connector between a first side flap and a second side flap of the patch electrode structure, and cause the first side flap and the second side flap to rise in a tilting manner, and lean against sides of the connector.
