Respirators like N95 masks are only effective if they fit properly. But due to the wide variation in human facial shapes, many masks don’t seal well. A poor fit lets dangerous particles like viruses, dust, or smoke in — making the mask nearly useless. Current solutions like user self-checks are unreliable, and professional fit tests are infrequent and slow, leaving users at daily risk.
The Innovation
This invention introduces a smart kiosk that checks if a respirator fits properly — in real-time, without user guesswork. It uses thermal imaging (like a heat camera) to detect tiny air leaks around the edges of the mask. It then shows the user exactly where the problem is on a screen using a simple traffic light system: green for good fit, red for leaks.
What Makes It Unique
Unlike anything on the market, this kiosk combines infrared (heat) cameras, machine learning (AI that learns from thousands of past examples), and real-time feedback. The system scans the mask while it’s on the face, detects leaks based on subtle temperature differences, and guides the user visually to fix the fit. This replaces guesswork with precision.
Real-World Benefits
- Instantly shows whether your mask works — no special training needed
- Pinpoints problem areas to improve safety
- Reduces the need for expensive, time-consuming professional fit tests
- Boosts confidence and protection for healthcare workers, miners, or anyone in high-risk settings
Broader Impact
This technology could revolutionize respiratory safety — especially during pandemics or in polluted environments. It helps industries protect workers better, improves public health, and ensures that protective equipment protects. It could even inform future designs of better-fitting respirators tailored to individual faces. This is a practical, science-backed upgrade to how we ensure respirators work — and could save lives by preventing false confidence in poorly fitted masks.
