Self-Powered VOC Gas sensor

According to the World Health Organisation (WHO), 10 million deaths occurred only because of cancer in 2020, and this number is increasing every year. One of the major reasons is the late detection of disease which is the worst part of this technological era. We really need smart technology which can help in the early detection of cancer disease. Due to abnormal metabolism, the concentration of emission of VOCs changes before any tumor formation, hence this will be the best way to detect cancer at an early stage. I am working on the best perovskite lead-free material which will facilitate a self-powered VOC gas detector.
