Mask with cough disease detection function

2022: Device Announcement

In early August 2022, the University of Missouri introduced a smart mask capable of tracking diseases by analyzing coughs. Engineers have turned to developing soft bioelectronics that can track a user's physiological state based on their cough.

Thanks to the technology of flexible bioelectronics, which is built into the mask and developed using laser production (LP). In this case, laser engineers applied a conductive metal, photoactive transition metal oxide (molybdenum dioxide) to soft elastomers coated with molybdenum chloride precursors under ambient conditions. The material has high electrical conductivity, chemical stability and biocompatibility, even in magnetic resonance imaging (MRI). In addition, the LP can be made on a variety of substrates, including polymers, glass, and hair.

A smart mask is presented that determines cough diseases

When embedded in a face mask, bioelectronics, which functions by determining the distance between the built-in antenna and the user's face, which changes the signal depending on the intensity and frequency of the cough. It can also be used to determine whether the mask is worn properly to maintain its effectiveness. According to the developers, the mask works in conjunction with a smartphone that collects relevant data and sends information to medical professionals who can track the potential spread of the virus.

As for the wear and tear of sensors and substrate materials over time, engineers argue that while the sensors can be reused, current tests show they only work for one day. However, additional tests will be carried out to improve the design. In addition to smart masks, engineers argue that LP-based bioelectronics can be integrated into soft drives to create light-guided reconfigurable three-dimensional architectures, variable air flow sensors and robotic worms with bioelectronic sensors. They can also be used to monitor the user's breathing for the purpose of diagnosing other diseases, including sleep apnea, and to monitor other biometric parameters, including vital signs in real time.^[1]
