Electroencephalography headset and system for collecting biosignal data

The headset of claim 0, further comprising a first support block:

• rigidly mounted to the first band between the first electrode and the second electrode;
• extending toward a median of the lateral axis spanning the left junction and the right junction;
• and
• defining a first surface facing the lateral axis and configured to rest against a head of a user.

headset of claim 10, further comprising a second support block:

• rigidly mounted to the first band adjacent the second electrode laterally opposite the first support block;
• extending toward the median of the lateral axis;
• and
• defining a second surface facing the lateral axis and configured to rest against the head of the user.

The headset of claim 11, wherein the second electrode comprises:

• an electrode body coupled to the first band;
• an electrode tip coupled to the electrode body opposite the first band;
• and
• a spring element:
• arranged inside the electrode body;
• configured to bias the electrode tip past the first surface of the first support block and the second surface of the second support block toward the median of the lateral axis;
• and
• configured to apply a force to the electrode tip to depress the electrode tip against a scalp of the user.

An adjustable electroencephalography headset comprising:

• a set of adjustable bands arranged between a left junction and a right junction;
• a set of fixed electrodes arranged at a set of fixed positions along the set of adjustable bands;
• a set of band adjusters configured to adjust a length of the set of adjustable bands about a head of a user while maintaining the set of fixed positions;
• a set of adjustable electrodes arranged at adjustable positions with the set of adjustable bands;
• and
• wherein the set of band adjusters and the set of adjustable electrodes are configured to cooperatively position the set of fixed electrodes and the set of adjustable electrodes in a 10-20 electroencephalography electrode configuration.
