Abstract

Disclosed are dielectric barrier discharge (DBD) devices and methods of use for sterilizing surfaces. The DBD devices generally include one or more first electrodes, one or more second electrodes or chemical reagent layers, and at least one dielectric layer between the one or more first electrodes and the one or more second electrodes or chemical reagent layers. In various configurations, the at least one dielectric layer is either (a) in contact with at least one of the first electrodes or (if present) at least one chemical reagent layer, or (b) is separated from the one or more first electrodes by a first gap and is also separated from the one or more second electrodes or chemical reagent layers by a second gap.

Dependent claims

A dielectric barrier discharge (DBD) device, comprising:

one or more first electrodes;
one or more second electrodes or chemical reagent layers;
at least one flexible dielectric layer between the one or more first electrodes and the one or more second electrodes or chemical reagent layers;
a first semipermeable layer in contact with an outward-facing surface of the first electrode;
a second semipermeable layer in contact with the outward-facing surface of the one or more second electrodes,
wherein the at least one dielectric layer is in contact with a planar surface of the one or more first electrodes on a first surface of the at least one flexible dielectric layer, and is in contact with a planar surface of the one or more second electrodes or chemical reagent layers on an opposite surface of the at least one flexible dielectric layer,
wherein the DBD device is configured to function without fluid flow,
wherein the one or more first electrodes and the at least one dielectric layer are flexible, and
wherein the DBD device is configured to ignite surface dielectric barrier discharges.
