Wearable device for remote monitoring of transcutaneous tissue oxygenation
2021
Wearable devices have found widespread application in recent years as consumer electronics for sports and health tracking. A metric of health which is overlooked in currently available technology is the measurement of oxygen in living tissue, a key component in the cellular energy production. We report on the development of an optical wireless wearable prototype for transcutaneous oxygen monitoring based on the phosphorescence emission of a highly breathable oxygen sensing film. The device is truly wearable, weighs under 20 grams,is completely self-contained, requires no external readout electronics and is highly sensitive to oxygen in the physiological range.
