A team of Chinese scientists have developed a wearable bioelectric mask that can detect respiratory diseases in the air, including Covid-19 and influenza, and report results in 10 minutes.
Once connected to a wireless network, the mask can transmit real-time data to a user’s mobile device, including detection alerts, according to a study published in the peer-reviewed journal Matter on Monday.
The mask is intended to be used as an early warning system to prevent future outbreaks of respiratory infectious diseases, researchers said.
These diseases are spread through the air by droplets or aerosols. But direct detection of viruses in the air can be difficult as the concentrations can be extremely low.
To tackle the problem, researchers from Tongji University in Shanghai developed a wearable electronic device equipped with highly sensitive ion-gated transistors capable of detecting low concentrations of viral proteins found in various respiratory infectious diseases, including Covid-19, and H1N1 and H5N1 strains of flu.
To test the mask, researchers placed the device in a sealed chamber and then sprayed gas containing very small amounts of viral proteins – Covid-19, H1N1 and H5N1 – into the space.
