Wearable Sensor Measures Muscle Oxygen Levels

Humon’s Humon Hex debuts as a wearable that helps athletes understand the limits of their body and prescribes the perfect pace and workout intensities in real-time by measuring how muscles use oxygen, reportedly the best measure of exertion. It is detailed as the first clinically validated wearable to use optical sensors to noninvasively monitor the oxygen levels in the muscle. Unlike the common wrist worn wearables, the Humon Hex has been designed to be worn on the thigh to measure oxygen saturation in the quadriceps. This muscle group was chosen to be monitored because it is the most exerted muscle for most endurance athletes.


Using localized muscle information, the Hex provides personalized training insights that help athletes improve their performance. The athlete is guided by the Hex through the display of colored training zones that athletes use to pace themselves optimally. These insights are provided on a phone, watch, or bike computer in real time. Through this analysis, the Hex provides:
