Engineers from MIT and Harvard created disposable sensors that can be adapted to face masks to detect if the user has Covid-19
The face mask has become one of the most used elements during the pandemic by the Covid-19. Over time they have been improved to offer greater protection to users.
Engineers from the Massachusetts Institute of Technology (MIT) and Harvard University created a face mask what is capable of detect if he user has Covid-19 in minutes.
They are disposable sensors that can be adapted to masks and work like the PCR tests.
“It works with any mask and combines the high precision of PCR testing with the speed and low cost of antigen testing”
They can also detect other pathogens and toxins as they were developed to find viruses like Ebola and Zika. It should be noted that the project began three years ago, but with the onset of the pandemic there was a new approach.
According to its developers, they have a lyophilized cell mechanism, it is a conservation technique based on dehydration.
How does the mask developed by MIT and Harvard engineers work?
The face mask that detects if the user has Covid-19 It has a small water tank, which is released by pressing a button.
Releasing the liquid hydrates the lyophilized components of the sensor to detect the virus. The breath drops accumulated inside are immediately analyzed.
After 90 minutes, users will be able to see the results. In this sense, only the user will be able to know the results since it is only displayed inside, so the privacy of the person is respected.
“If there is no coronavirus, there will be no type of reaction. If there is little, there will be, but it will hardly be detected. And if there is a lot, more copies will have been obtained and this reaction will be more remarkable “
The engineers have already applied for the patent and hope to work with a company soon to be able to further develop the sensors used in the face mask that detects if the user has Covid-19.
This is another way to detect the coronavirus and prevent its spread. However, in the future it could be used in other elements such as the gowns of scientists who work with dangerous biological material.
There has even been thought of uniforms of military or rescue personnel in places where substances such as nerve gas have been spilled.
