Abstract: A wearable, miniaturized wireless device provides accurate measurement of transcutaneous carbon dioxide diffusing though the skin detects a luminescent response of a carbon dioxide-sensitive film, providing an accurate reflection of a person's blood carbon dioxide levels. The device employs a charge-to-digital converter (CDC) architecture operable for implementation of a time-domain dual lifetime referencing computation to measure transcutaneous carbon dioxide. This potential product enables highly accurate and precise measurements of transcutaneous carbon dioxide while minimizing interference from confounding factors.
