Singapore researchers are expanding the role of masks in fighting infections, using them as tools to monitor the wearer's vitals and check for COVID-19 indicators.

Scientists have developed a technology that allows you to turn any mask into a "smart" one. Such a mask can monitor the wearer's vital signs such as heart rate and body temperature in real time.

Chip-like sensors attached to the mask can measure skin temperature, blood oxygen saturation, blood pressure and heart rate. Owner abbreviations are all parameters that are related to COVID-19.

As with other smart wearable devices, here data is transmitted from sensors to the device using Bluetooth.

"He equipped with a built-in LED device that allows light to pass through the skin to the capillaries.So, for example, we can expect capillary expansion when blood pressure is high, and the change in size can be calculated using the LED," explained Luo Xian Jun Professor Institute and Materials and Engineering Research under the Agency for Science, Technology and Research.

A team from Nanyang Technological University and the Agency for Science, Technology and Research said that masks can be used both to prevent COVID-19 disease, and for health monitoring in places like nursing homes and healthcare facilities.
The scientists behind the technology say that if patients use these "smart" masks, it will save nurses the need to walk from bed to bed and move large and bulky medical equipment from room to room to monitor patients' vital signs, and thereby reduce the chance of reinfection and help protect healthcare workers.

Researchers are currently negotiating with hospitals about conducting clinical trials of masks and evaluating the effectiveness of the technology in real conditions.

Current laboratory data shows a deviation of three to five percent when comparing measurements using smart masks with standard medical equipment.

In addition In addition, there is also some concern about the public acceptance of such masks.

"I think it's a very strange feeling when there is a gauge in the face mask that touches the cheek. I'd rather have the same technology applied to an arm or wrist bandage," said Leong Ho Nam, an infectious disease specialist at Mount Elizabeth Novena Hospital in Singapore.

To overcome some of these problems and make the chip is less abrasive for the wearer, scientists have coated the sensors with a waterproof, skin-like silicone material.

They have also significantly reduced the number of tips from three to one sensor, which is about the size of an adult's thumb.

But whether these measures will encourage people to put sensors in their masks, which is not so convenient for some, remains to be seen.
