Appl.No 17566078 Applicant COMMISSARIAT À L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES Inventor Hicham MASKROT

A manufacturing method enabling the obtainment of a functional part essentially formed in a metallic material, all or part of the functional part delimiting a filtering medium permeable to a fluid and delimiting first and second main faces for a preferred circulation of the gas through the filtering medium. The method includes a main phase consisting of an additive manufacturing method in successive passes from a support tray. Each pass includes the deposition of at least one layer of the metallic material, the deposited material adhering to the metallic material deposited before. The deposition is controlled at each pass so the stack of metallic material constitutes the functional part. The filtering medium includes a coalescent network of connecting strands interconnected according to a three-dimensional spatial distribution between the faces, the connecting strands of the network delimiting therebetween pores spatially distributed within the filtering medium in three dimensions between the faces.

A smart mask including sensors, an RFID tag, a microcontroller and a communications device communicates by a near field communications protocol with a WiFi access point, which sends sensor readings, a location, and an identification to a cloud based smart mask monitoring application, which registers the smart mask, and stores the identification. The sensor readings are analyzed by the cloud based smart mask monitoring application to determine when a person wearing the smart mask may be contaminated by COVID-19. A neighborhood analysis is conducted to identify other smart mask wearers who may have come in contact with the contaminated person, and the other smart mask wearers are notified. Instructions are sent to the microcontroller to activate LEDs which indicate whether the health status of the person is normal, is possibly infected or is contaminated. A smart phone including a native smart mask monitoring application may display the health status.
