1. A head-mounted physiological signal monitoring system comprising:
- a headgear apparatus comprising a hat, helmet, earpiece or eyeglasses to fit snugly to, and place light pressure on, a head or in an ear of a subject, and a plurality of electrode connectors attached to or integrated into the headgear apparatus;
a plurality of dry electrophysiological electrodes to acquire electrophysiological signals and to be attached to the electrode connectors, each dry electrophysiological electrode of the plurality of dry electrophysiological electrodes comprising a lower surface to contact the subject'"'"'s skin, and a plurality of low aspect ratio protruding surface features on the lower surface; and
at least one electronic component including a processor comprising an algorithm to process the electrophysiological signals,wherein the processor is to at least in part process the electrophysiological signals to obtain electrocardiogram (ECG) signals.
