Abstract
Methods, systems, and devices are disclosed for acquiring and analyzing physiological signals. In one aspect, a physiological sensor device includes a substrate formed of an electrically insulative material and structured to allow physical contact of the device with the frontal region of the head of a user, a recording electrode configured at a first location on the substrate to acquire an electrophysiological signal of the user, a reference electrode configured at a second location on the substrate to acquire a reference signal to the electrophysiological signal, and a ground electrode configured at a third location at least partially between the first and the second locations on the substrate, in which the first location is posterior to the second and third locations, and in which the device is operable when electrically coupled to an electrical circuit to detect physiological signals of the user.
