Wireless system can sense when masks are properly decontaminated in moist-heat
For moist-heat decontamination to properly sanitize N95 facemasks, the conditions have to be perfect. If the temperature or humidity are even the slightest bit too low, then dangerous pathogens can survive the process, putting mask-wearers at risk for infection.
Researchers at Northwestern University, University of Michigan and University of Florida have developed a new wireless sensor platform takes the guesswork out of decontaminating N95 facemasks. By sensing temperature and humidity and tracking time, the inexpensive sensor ensures that conditions are ideal for decontaminating masks.
The researchers tested the platform, called VeriMask, in the laboratory as well as in real clinical settings. The sensor was able to ensure proper decontamination conditions for hundreds of masks simultaneously, while users monitored the process in real time with a smartphone app.
