Plasma Source Array for Treatment of Freeform Surfaces

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is a device designed for plasma treatment of surfaces of any shape. It utilizes an array of dielectric barrier discharge (DBD) pin electrodes that are arranged next to one another in a plane and can move axially. This allows the pins to adapt their positions to match the form of the surface being treated when applied, ensuring effective plasma contact even on uneven or curved surfaces.

Use CasesContent extracted from patent full text and abstract with AI.

• Medical sterilization of irregularly shaped surgical instruments or implants
• Surface modification or cleaning of complex 3D parts in manufacturing
• Disinfection of packaged food items with uneven shapes
• Treatment of skin or wounds in medical therapies involving plasma
• Surface activation or coating in electronics or automotive components

BenefitsContent extracted from patent full text and abstract with AI.

• Allows uniform plasma treatment on surfaces with complex or irregular shapes
• Improves effectiveness and reliability of plasma processing by adapting to the surface contour
• Enables automation or streamlining of surface sterilization or modification processes
• Reduces the need for manual adjustment or custom fixtures for each new part or shape
• Can potentially increase the safety and efficacy of plasma-based medical or industrial procedures

Patent Abstract

Vorrichtung zur Plasma-Behandlung von beliebigen Oberflächen mittels dielektrisch behinderter Entladungen (DBE), umfassend DBE-Stiftelektroden, die nebeneinander in einer Ebene zu einem Array angeordnet sind und axial frei beweglich sind, so dass sich die Position der Stiftelektroden beim Aufsetzen auf die zu behandelnde Oberfläche an deren Oberflächenform anpasst.
