Headset for transcranial direct-current stimulation, tdcs, and a system comprising the headset

A headset, comprising:

• a frame configured to fit across a forehead of a user;
• a first electrode coupled to the frame at a first end portion of the frame such that the first electrode is configured to be disposed on a first side of the forehead when the frame is fitted across the forehead;
• a second electrode coupled to the frame at a second end portion of the frame such that the second electrode is configured to be disposed on a second side of the forehead when the frame is fitted across the forehead, the first and second electrodes collectively configured to provide transcranial stimulation to the user when in contact with the first and second sides of the forehead;
• a bracket coupled to a center portion of the frame, the bracket configured to extend from the frame, over a top of a head of the user, and to a back of the head when the frame is fitted across the forehead, the bracket configured to support the frame when fitted across the forehead to ensure that the first and second electrodes are disposed on the first and second sides of the forehead;
• and
• a processor operatively coupled to the first and second electrodes, the processor configured to control the first and second electrodes to deliver current to a brain of the user to provide the transcranial stimulation.

A headset, comprising:

• a frame defining an elongated arch sized to fit across a forehead of a user;
• a first electrode disposed at a first end portion of the frame;
• a second electrode disposed at a second end portion of the frame;
• and
• a longitudinal extension having a first end coupled to a center portion of the frame and a second end that terminates in a support structure configured to contact a back of a head of the user,
• the frame and the longitudinal extension configured to be positioned on the head such that (1) the frame extends across the forehead of the user and places the first electrode in coupling with a left side of the forehead and the second electrode in coupling with the right side of the forehead and (2) the longitudinal extension extends toward a back of the head with the support structure in contact with a back of the head,
• the first and second electrodes collectively configured to provide transcranial stimulation to the user when in coupling with the left and right sides of the forehead.

A headset, comprising:

• a frame;
• a first electrode disposed at a first end portion of the frame;
• a second electrode disposed at a second end portion of the frame, the frame configured to be worn on a forehead of the user such that the first and second electrodes are in coupling with first and second sides of the forehead and are configured to deliver current in a predetermined direction to the user to provide transcranial stimulation;
• a longitudinal extension having a first end coupled to a center portion of the frame and a second end extending away from the frame, the longitudinal extension being shaped to extend over a head of the user such that the longitudinal extension prevents the frame from being worn in an orientation in which the current delivered by the first and second electrodes is reversed;
• and
• a processor operatively coupled to the first and second electrodes, the processor configured to control the first and second electrodes to deliver the current.
