EEG Headband with Improved Amplifier Attachment Shape Conformity, Electrode Placement, and Gel Delivery Functionality

Abstract

Systems and methods for electroencephalography headband apparatuses including a strap member, an amplifier device, and electrode assemblies each including a capsule receiving structure having a detent feature configured to resist rotation of a gel capsule positioned there within, a stabilization structure having a central attachment section and a plurality of leg members positioned radially outward from a central axis of the electrode assembly, and a gel delivery structure configured to be positioned at least partially within the capsule receiving structure and to rotatably attach to the stabilization structure such that the gel delivery structure may be able to rotate independently of the stabilization structure. The gel delivery structure may include a plurality of teeth members configured to engage with and lacerate a lower surface of the gel capsule and a plurality of gel delivery channels configured to deliver gel from the gel capsule to patient scalp.
