3D-printed 'electric nose' can SNIFF out COVID-19 in just 80 seconds with 94% accuracy

New technology aims to speed up coronavirus testing by'sniffing' the patient's nasal cavity and produce a diagnosis in just 80 seconds. Scientists at the Weizmann Institute of Science in Israel designed a 3D-printed electric nose that analyzes aromas of chemicals in those infected with COVID-19. Dubbed Pen3, the instrument consists of a long tube fitted with sensors, which fits into the nostril to analyze the naval cavity. Deep learning algorithms sniff around the nose and return real-time detection of COVID-19 infections – and with 94 percent accuracy. New technology aims to speed up coronavirus testing by'sniffing' the patient's nasal cavity and produce a diagnosis in just 80 seconds Project leader Professor Noam Sobel said in a statement: 'The e-nose generates a pattern in every odor – it characterizes the smell of COVID-19.
