Abstract
In recent years, the development of sensors capable of detecting acetone levels has garnered attention in health monitoring and personalized medicine. Acetone in the body, a ketone body produced during metabolic processes, has emerged as a promising biomarker for various health conditions, including diabetes, obesity, and metabolic disorders. Its presence in exhaled breath offers a non-invasive means of assessing metabolic health, presenting a unique opportunity for continuous monitoring and early intervention. This research investigated the use of a PANI/PMMA polymer sensor array to measure acetone gas. Breath samples and standard substances (acetone, butyric acid) were collected using a hygienic mask and measured with an electronic nose device. The tests showed the sensor could classify between a blank mask, acetone, butyric acid, and breath odors.
