SPYRAS develops ‘Smart Mask’ to track wearer’s respiratory patterns

Analytics platform SPYRAS has created a ‘Smart Mask’ that displays respiratory information in real time.

 Using SPYRAS paper sensor technology, the mask aims to provide users with actionable information about their respiratory function in order to improve the user’s health and indicate abnormal breathing trends.


The sensor attaches to masks that allows users to track their respiratory performance in real time. Users can play games, follow breathing exercises to reduce anxiety and stress, and monitor their mask’s filter efficiency— all from their mobile phone. Cloud- based algorithms then look at the data in comparison, taking into account external factors, such as weather, pollen and pollution, to analyse external outside conditions that could affect users breathing.

Using humidity changes on inspiratory and expiratory air flow to detect conductivity changes of paper, the sensing technology provides a highly accurate, non-invasive and disposable sensor that can be placed directly into mask filters. When the filter needs to be replaced or the user wants to wash their mask, they will first be notified of the decrease in filter performance ahead of time. When changing or washing a mask, the electronics module twists away to detach and can be reused later. The sensor is then disposed of to keep the mask sterile, with a replacement in its place.

SPYRAS was one of 800 businesses selected amongst 8000 applicants for the Innovate UK “business-led innovation in response to global disruption” award, proposing a sensor that would fit into any mask and connect to a mobile app for users to visualise their respiratory function as they wear the mask. The devices were then tested at the Medical Devices Testing and Evaluations Centre (MD-TEC) at the University Hospitals Birmingham Trust to compare the product against ventilator standards of testing. Using a minute breathing rate average from the SPYRAS sensors against ventilator standards, the test showed SPYRAS was able to track breathing rate at a 99.5% accuracy.


George Winfield, Founder and CEO of SPYRAS, said, “The team suggested in March that we should place one of our sensing technologies directly into the filters of masks to track respiratory rates. We created a concept video of an early prototype and placed it onto social media which seemed to catch people’s imagination and maybe say that this wasn’t such a crazy idea.

“ We were thrilled to have been supported by Innovate UK in this project and the team have showcased their talents by delivering an entirely new product and back end platform in only a three-month window, complete with a usability trial at the MD-TEC test centre going up against ventilator testing standards for respiratory monitoring. This product has the potential to expand into remote telemonitoring and assessment of respiratory conditions.”


The device will now enter user trials to allow for feedback on the features and applications before market entry for in early 2021.
