The 3D printed “electric nose” can detect COVID-19 in just 80 seconds with an accuracy of 94%
- The device consists of a long hose with sensors that fits into the marine cave na
- The nasal cavity is analyzed through deep learning, which looks for specific smells
- Patients infected with COVID-19 emit chemicals that give off an aroma
- The system can make a diagnosis in just 80 seconds and with an accuracy of 94%
New technology aims to speed up coronavirus tests by “sniffing” the patient’s nasal cavity and making a diagnosis in just 80 seconds.
Scientists at the Weizmann Institute of Science in Israel have developed a 3D-printed electric nose that analyzes the aromas of chemicals in people infected with COVID-19.
The instrument, known as the Pen3, consists of a long tube fitted with sensors that fits into the nostril to analyze the marine cavity.
Deep learning algorithms sniff around the nose and provide real-time detection of COVID-19 infections – with an accuracy of 94 percent.

Project leader Professor Noam Sobel said in a statement: “The e-nose creates a pattern in every smell – it characterizes the smell of COVID-19.
“We’re teaching him to smell coronavirus.”
The researchers trained Pen3 to identify volatile organic compounds (VOCs) in the inner nasal passage.
The tests were performed on 503 people and Pen3 was able to correctly identify 27 with coronavirus.

“Every disease has a smell because it changes metabolic processes. Metabolic products have a smell, ”explains Sobel.
Originally designed for raising visors, Pen3 is attached to an electric lift that goes up to the person’s window so they can stay in their vehicle during the process.
“When a connection interacts with the sensors, there is an exchange of oxygen, which leads to a change in electrical conductivity,” says Sobel.
Sobel and his team believe the technology will be used to test large congregations and inside airports to reduce waiting times at other test locations.

The technology takes inspiration from previous work that found dogs to be able to sniff out infections.
A study published on May 23 found that sniffer dogs are more effective than rapid tests at detecting cases of Covid-19.
Amazingly, the dogs are able to detect up to 94 percent of cases – and are therefore significantly more accurate than quick lateral flow tests.
The authors said their results “exceeded all expectations” and that dogs could be used in workplaces, theaters and stadiums to help Britain return to normal.
Scientists from the University of Durham and the London School of Hygiene and Tropical Medicine (LSHTM) are currently in discussions with the Department of Health and the World Health Organization about the use of dogs in airports.
They said two dogs could screen 300 passengers coming off an airplane for COVID-19 in just 30 minutes.
Individuals identified as positive by the dogs were then given a PCR test to confirm the results.
The pandemic began in Wuhan, China, with the first reports of an outbreak on December 31, 2019. From there, the virus spread across the world.
