Can a Melanin-Sensing oximeter end hidden oxygen reading bias?

This trial tests a new wearable device, MABOS, that aims to adjust blood oxygen readings based on skin melanin levels. Standard pulse oximeters can be less accurate on darker skin, and this study enrolls healthy adults with diverse skin tones to see if MABOS is safe, comfortable, and able to estimate melanin and oxygen. Participants wear both MABOS and a standard oximeter while performing breathing exercises, and their skin is monitored for irritation. The goal is to gather early evidence on whether this approach could improve oxygen monitoring for people of color.
