Abstract

A headwear assembly is provided that measures physiological changes, e.g., oxygen saturation, pulse, blood pressure, and body temperature of a user during physical exercise, to include athletic activities and other situations. The headwear assembly can provide integrated functionality with an external device such as a smart phone. The headwear assembly can be embodied in various configurations, e.g., stand-alone headband, cap, visor, or a helmet.
