Scientists Claim New 3D-Printed ‘Electric Nose’ Can SNIFF Out Coronavirus In 80 Seconds With 94% Accuracy


=== (AGENDAWATCHDOG) === New technology aims to speed up coronavirus testing by ‘sniffing’ the patient’s nasal cavity and producing 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. 

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.

‘We are teaching it to smell coronavirus.’ 

Researchers trained Pen3 to identify volatile organic compounds (VOCs) in the inner nasal passage.

Testing was done on 503 people and Pen3 was able to correctly identify 27 with coronavirus
