Biometric acquisition device

A biological signal acquisition device comprising:

• a first electrode and a second electrode configured to be in contact with a living body and configured to acquire a biological signal emitted by the living body when the first electrode and the second electrode are in contact with the living body;
• and
• a first elastic body configured to press the first electrode against the living body when the first electrode is in contact with the living body.

A method comprising:

• contacting a first electrode and a second electrode with a living body, wherein contacting the first electrode with the living body comprises pressing, by a first elastic body, the first electrode against the living body;
• and
• acquiring, by the first electrode and the second electrode, a biological signal emitted by the living body when the first electrode and the second electrode are in contact with the living body.
