Volatile Organic Compounds (VOC) and non-VOC associated with the Cannabis use are present in the exhaled breath within the first few hours of inhalation. Traditionally, the presence of these biomarkers is detected using the conventional Gas Chromatography-Mass Spectrometry (GC-MS) system. GC-MS can also measure concentration level of these biomarkers in a unit volume with high accuracy. However, these systems are often bulky and highly specialized. Therefore, this project investigates the development of a miniaturized sensor to detect the targeted biomarkers associated with Cannabis use in the exhaled breath. Advanced micromachined sensor systems are emerging as practical, non-invasive and sensitive diagnostic tools due to their potential for integration into portable electronics, device miniaturization, low power consumption, low cost and high fabrication yield. They leverage advanced microfabrication techniques that transfer significant benefits of micromachining and integration to the fields of medicine and environmental monitoring. In this work, a micromachined sensor prototype will be designed and fabricated that can provide a real-time detection of desired biomarkers at the physiologically relevant level. This technology provides potentials for integration and therefore, can address the company's current challenges and needs of incorporating a miniaturized system.**
