Force-controlled electroencephalogram monitoring device

An electroencephalographic (EEG) headset comprising:

• a housing unit configured to be positioned on the top of a head of a user;
• a first arm connected to the housing unit and having a first spring-loaded electrode holder on an end, the first spring-loaded electrode holder comprising a first electrode formed from a conductive material, a spring connected to the first electrode and configured to maintain the first electrode in contact with the skin of the user with a consistent amount of force, an interface connected to the spring and configured to form a conductive connection between the spring-loaded electrode holder and the housing unit, and a conductive path between the first electrode and the interface, wherein the first arm is configured to hold the first electrode in contact with a first region of the head of the user with a first amount of force due to a curvature of the first arm, the first arm has at least one straight region and the first arm has at least one straight and at least one curved region between the housing unit and the first electrode at least one curved region between the housing unit and the first electrode, and the first arm is not in direct contact with the head of the user;
• and
• a second arm connected to the housing unit and having a second spring-loaded electrode holder on an end, the second spring-loaded electrode holder comprising a second electrode formed from a conductive material, a spring connected to the second electrode and configured to maintain the second electrode in contact with the skin of the user with a consistent amount of force, an interface connected to the spring and configured to form a conductive connection between the spring-loaded electrode holder and the housing unit, and a conductive path between the second electrode and the interface, wherein the second arm is configured to hold the second electrode in contact with a second region of the head of the user with a second amount of force greater than the first amount of force due to a curvature of the second arm, the second arm has at least one straight region and/or at least one curved region between the housing unit and the second electrode, and the second arm is not in direct contact with the head of the user.
