Exhaled breath analysis is a burgeoning research field, with a focus on the capabilities of a groundbreaking graphene-based breath sensor for disease detection. The study aims to unveil the sensor's potential as a non-invasive tool for diagnosing various health conditions by examining exhaled breath constituents. The methodology involves meticulous preparation of a graphene solution, deposition onto a silver paste electrode using a precise drop-casting method, and a critical 30-minute thermal annealing process. Characterization through Scanning Electron Microscopy (SEM) provides insights into the sensor's surface, while current-voltage (I-V) analysis explores its electrical behaviour. Discernible responses underscore the sensor's efficacy in detecting breath constituents, with impressive performance metrics, including response and recovery times, enhancing its credibility. The experimental findings affirm the commendable sensing capabilities of the graphene-based breath sensor, emphasizing its potential as a reliable tool in disease detection and contributing to the evolution of non-invasive medical technologies. © 2024 Wydawnictwo SIGMA-NOT.
