Paper Abstract

We developed a wearable system for wireless monitoring of oxygenation of deep tissues such as liver and lung during exercise. It is also useful where subcutaneous fat thickness is high. Our system utilizes Continuous Wave Near Infrared Spectroscopy (CW NIRS) with source-detector distances from 10mm to 60mm. This allows us to observe tissues at various depths. To mitigate the interference of the overlaying tissue layers such as skin, fat and muscle, we developed a multi-layer Monte Carlo model for photon diffusion. Flexible structure of our device helps achieve better skin contact and expand its usability to most body parts.
