But doubts still linger over its accuracy because of a lack of transparency in its development. GeNose was developed by UGM associate professor of physics Kuwat Triyana and UGM pediatric clinician Dian Kesumapramudya Nurputra. It is based on an artificial-intelligence-powered sensory system that mimics the human nose to detect volatile organic compounds, which, according to its researchers, are specific to people with COVID-19, exhaled by a person into a plastic bag.
