Abstract: Example headsets and electrodes are described herein. Example electrode units described herein include a housing having a cavity defined by an opening in a side of the housing and an electrode. In some such examples, the electrode includes a ring disposed in the opening and an arm, where the arm has a first portion extending outward from the opening away from the housing and a second portion extending from an end of the first portion toward the housing and into the cavity, and the first and second portions connect at a bend.

Abstract: Example headsets and electrodes are described herein. Example electrode units described herein include a housing defining a cavity, conductive paste disposed on an inner wall of the cavity and an electrode disposed in the cavity and spaced apart from the inner wall of the cavity. The electrode extends from the cavity, and the conductive paste is to shield the electrode from noise.

Abstract: Electrodes and electrode units for gathering electroencephalographic data are described herein. An example electrode unit includes a housing and an electrode coupled to and extending from the housing. The electrode includes a first shell, a second shell retractable relative to the first shell, a third shell retractable relative to the second shell, and an electrode pin retractable relative to the third shell. The first shell, the second shell, the third shell, and the electrode pin are configured in a telescoping arrangement and moveable between an expanded state and a compressed state. The electrode includes a spring to bias the second shell outward from the first shell, the third shell outward from the second shell, and the electrode pin outward from the third shell to contact skin of a subject.

Abstract: Example headsets and electrodes are described herein. Example electrode units described herein include a guide defining an opening and an electrode disposed in the opening. The electrode has a housing, a spring, and a pin. The pin is biased outward from a first end of the housing via the first spring. The example electrode units also include a second spring disposed over the opening adjacent a second end of the housing.
