Wearable Sensor Measures Light Emission on Skin to Monitor Tissue Oxygenation

Researchers have combined an oxygen-sensing film and machine learning to create a wearable sensor capable of measuring tissue oxygenation through a person’s skin. Developed by researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital and Harvard Medical School, the sensor works by detecting the phosphorescence lifetime and intensity of the acrylic oxygen-sensing film that adheres to the skin … The researchers said that the wireless sensor can monitor oxygen levels on a continuous basis and is easy to operate, making it suitable for remotely monitoring oxygen levels outside of health care settings …
