The mask knows 'Vietnamese phone calls'

Air filter, phone call, music listening are the features integrated by inventor Tran Ngoc Hieu (Ho Chi Minh City) in a smart mask, which helps pedestrians not stop.

Smart masks can listen to music, listen to the phone

Masks are useful for everyone, especially when environmental pollution is increasing. However, items sold on the market currently do not have a filter layer so the effect on users is very little or almost none.

From the above reality, Tran Ngoc Hieu has created a smart mask , with many built-in features such as better air filtration, reducing diseases related to the lungs and throat; heating in winter; listen to music and phone.

The facepiece is 15x17cm in size, hand-sewn with natural silk material. It has three active filter layers squeezed together so it has the ability to filter air, limit respiratory diseases.

Smart masks.

Inside masks, Hieu and colleagues integrate circuit boards such as central control, audio processing, wireless connectivity, battery discharge monitoring, temperature control. It is connected to the phone via bluetooth. The two sides of the ear are equipped with stereo speakers with a frequency of 100-15,000 Hz. In front of the nose and mouth are thermal resistors and sensors such as temperature, sound, and capacitive sensors. The inner folds help users to disassemble everything for washing.

The entire product is run with an application on the phone. With the design on the user can listen to the phone when going outside without stopping; or entertainment listening to music on buses, public places. It even helps provide the traffic and weather situation where users need it.

When there is an incoming call, the responsive touch mechanism on the mask helps the user just need a swipe to wear a mask while talking without stopping the phone. When traveling on a bus, users can both listen to music and learn foreign languages ​​more easily.

The front of the mask is also equipped with a heating feature in the winter , by warming the air that the user inhales into the lungs. "It is no different from normal masks, but more beautifully designed. The charging time is 3 hours and can be used continuously for 2-3 months, if not using music and heating features" , Hieu said.

Hieu said, he and his colleagues are upgrading software to improve and are expected to put into production next month with many new features such as balancing the skin moisture for women in the winter.

"Application of high technology into conventional products is the direction I pursue to create many useful products that people need", Hieu said.
