摘要： A macro electrically active mask includes two conductive layers separated by at least one filtering and insulating layer. The conductive layers are connected to each other by a power source. The power source includes an oscillator and a high voltage transformer. The power source generates a periodic voltage with a fundamental frequency and multiple harmonic frequencies. The power source is connected between the two conductive layers and the periodic voltage generates a periodic electric field between the two conductive layers. The fundamental frequency, the duty cycle, and the amplitude of the periodic voltage are configured to inactivate the microorganism that pass through the electric field.

摘要： A mask with at least one filtering layer that includes a fabric made of non-conductive polymer fibers embedded with nanoparticles of two different metals is provided. The population density of the nanoparticles of the two metals on the surface of non-conductive polymer fibers is configured such that the adjacent nanoparticles of the two metals have an average distance of two micrometers or less. The two different metals are selected such that the electric field intensity generated between the nanoparticles of the two different metal through the aerosol particle inactivates the microorganisms that may be inside the aerosol particle. When an aerosol particle comes into contact with the nanoparticles of the two metals, the aerosol acts as an electrolyte between the two metal types and a potential difference and an electric field is generated, through the aerosol particle, between the nanoparticles of the two metals.
