  • Patent number: 11752233
    Abstract: A method for sterilizing ambient air includes the steps of: a) installing a plasma-based smart window including an atmospheric pressure plasma device which includes first and second transparent flat patterned electrodes sandwiched between a light-transmissive substrate and a light-transmissive cover plate; and b) applying a power supply parameter of a predetermined magnitude between the first and second transparent flat patterned electrodes at ambient temperature and pressure to generate a surface plasma proximate to the light-transmissive substrate or the light-transmissive cover plate so as to inactivate microorganisms in the ambient air.
    Type: Grant

  • Patent number: 11517852
    Abstract: A plasma air purifying device includes a container and at least one plasma-generating element. The container includes a container body, a plurality of first partition plates and a plurality of second partition plates. The container body has an air inlet, an air outlet, and an accommodating space between the air inlet and the air outlet, and the accommodating space includes a plasma zone and a reaction zone. The first partition plates and the second partition plates are staggered in the reaction zone to separate a plurality of reaction chambers. The reaction chambers integrate spatially first through channels of the corresponding first partition plates and second through channels of the corresponding second partition plates so as to form a repetitive bending reaction channel, such that the plasma can purify the air flowing through the air inlet, the plasma zone, the repetitive bending reaction channel and the air outlet.

  • Patent number: 11291744
    Abstract: An electrode component for generating large area atmosphere pressure plasma is provided. The electrode component comprises a first transparent insulation substrate, a first transparent electrode pattern, a second transparent electrode pattern, and a second transparent insulation substrate. The first transparent insulation substrate has a first thickness. The first transparent electrode pattern and the second transparent electrode pattern are formed on the upper surface of the first transparent insulation substrate and has a gap therebetween. The second transparent insulation substrate has a second thickness and covers the first transparent electrode pattern and the second transparent electrode pattern. The first thickness is greater than the second thickness in order to form atmospheric pressure plasma above the second transparent insulation substrate.
