Cold plasma treatment devices and associated methods

A cold plasma device, comprising:

• a housing having a high voltage electrical inlet port;
• a gas compartment disposed within the housing, wherein the gas compartment includes a gas inlet port to receive a gas flow and a gas outlet port, and wherein the gas compartment further includes an induction-grid-free environment;
• and a modular electrode disposed within the gas compartment, wherein the modular electrode is coupled to the high voltage electrical inlet port, wherein the modular electrode is configured to generate cold plasma for release via the gas outlet port, the cold plasma having a temperature in a range of 65 to 120 degrees Fahrenheit, and wherein the modular electrode is configured for easy insertion and removal from the gas compartment.

A method, comprising:

• providing gas to a gas compartment via a gas inlet port, the gas compartment being a magnet-free environment located within a housing having a high voltage electrical inlet port coupled to an electrode disposed within the gas compartment, and wherein the gas compartment further includes an induction-grid-free environment;
• and providing a pulsed voltage to the electrode via the high voltage electrical inlet port to thereby generate cold plasma for release via a gas outlet port of the gas compartment, the cold plasma having a temperature in a range of 65 to 120 degrees Fahrenheit, wherein the electrode comprises multiple size components configured to resonate at frequencies associated with a harmonic rich power signal received via the high voltage electrical inlet port.
