Xiaomi Smart Mask Patent Approved by USPTO: Trackable Wearer’s Breathing Quality

According tomedia reports, recently, due to the rising level of pollution in people’s living environment, masks and anti-pollution masks have become a mainstream product. In addition, with the outbreak of the new coronavirus in China, masks have become more important and increasing sales. Recently, the U.S. Patent and Trademark Office (USPTO) approved Xiaomi’s “smart mask” patent.

It is reported that the mask will be embedded with a computer unit, which contains a processor (processing all data from the mask on-board sensor), a size module (responsible for storing computing data), a battery (powering all devices), a connection module (to transmit all stored data) and a standard air filter.

According to Xiaomi, the smart mask also has a sensor that can be used to calculate “pollution absorption” and record the total wearing time of the mask. The processor then initiates a wireless connection through a pairing device, such as a smartphone, to transmit the user’s air breathing data to the app over a specified period of time. Once the data is transferred, the mask uses the air quality index data of the call center server to let users know the air quality in their city in real time.

In addition, the smart mask will likely be built into a health sensor that will be used to record data such as the amount of breath per user and the total number of breaths during wear. In addition, sensors such as common accelerometers and gyroscopes are included, and they can help masks determine whether the user is in motion during wear, because if it is in motion, it can have different results. These metrics will be consistent with the total amount of contaminants the user inhales, which will be extracted from the data obtained by the central server and sent to the mask by the paired phone.

Once the total intake of contaminants is calculated, the smart mask can compare this parameter with the filtration efficiency of the mask air filter to estimate the air quality the user is breathing in the current environment. In addition, it may even help users determine whether their lung capacity is increasing or decreasing. Given the current pollution in people’s living environments, such masks appear to serve as a wearable medical product that can potentially detect breathing abnormalities and recommend healthier breathing methods.

It is reported that the patent granted today was filed on June 15, 2016.
