Abstract

There is strong medical demand for continuous CO2 partial pressure (pCO2) monitoring. While there has been significant progress in the development of CO2 sensors, their implementation with optical wearable device remains under-explored. We have developed highly sensitive, rapidly responding, humidity insensitive and photostable CO2 sensing materials that can be used with optical wireless wearable device for real-time monitoring pCO2. The preliminary results reveal the prototype device is able to reliably detect reversible CO2 changes within physiological ranges.
