While standard surgical masks provide minimal protection, they do not adequately address issues that are specific to surgeons, such as fogging, discomfort, lack of breathability, and difficulty in communication during lengthy operations. The present project introduces a smart mask prototype specifically designed for surgeons as a means to resolve these problems. Major features include a multi-layered filtration system (medical-grade fabric, activated charcoal, HEPA filter), an integrated micro-fan for air supply, an ergonomically 3D-scanned fit, anti-fog valves, and a built-in microphone, which is optional. Developed by means of user-centred design, CFD simulations, and compliance checking (NIOSH/ISO), the mask prevents the entry of surgical smoke, harmful gases, odours, and ultra-fine particles (bacteria/viruses) while providing the possibility of reuse (20+ wash/wear cycles). The first tests show that there is a significant improvement in filtration performance, comfort, visibility, and ease of communication. Besides, there are opportunities for extensive clinical trials, cost savings, and environmental benefits.
