The invention pertains to a device designed for treating complex areas of human or animal skin, as well as plant surfaces, using cold atmospheric-pressure plasma. Central to this device is a gas-permeable electrode arrangement that generates a dielectrically impeded surface discharge. The grounded electrode is made of electrically conductive textile material, while the high-voltage electrode is a thin wire or conductive thread encased in a specific insulating layer. This configuration enables the generation of a flat plasma near diseased skin or wounds, facilitating treatment with minimal thermal and electrical stress. The flexible, gas-permeable textile structure allows for adaptation to variously curved surfaces and permits gas exchange with the environment or the targeted delivery of specific process gas mixtures into the active plasma zone.
