James Gary Eden (Inventor), Peng (Peter) Sun (Inventor)

Research output: Patent


An air fed mycoplasma device includes an array of elongate microchannels formed in a plastic or ceramic having tolerance to ozone and other radicals formed when plasma is generated from air in the microchannels. The microchannels include inlets configured to accept an air feed, and outlets configured to direct plasma jets toward a surface (which may be flat or internal to a pipe, for example) or object. An array of electrodes within the plastic/ceramic housing is configured to ignite and maintain plasma in the microchannels and is isolated by the dielectric from the microchannels. A supply intake for is configured to providing a plasma medium into the microchannels.
