Dielectric Barrier Discharge (DBD) is a type of electrical discharge that occurs between two electrodes separated by an insulating material, known as a dielectric. This setup allows for the generation of plasma at atmospheric pressure, which can be used in various applications, including surface treatment, ozone generation, and air purification. In a DBD system, a high voltage is applied across the electrodes, creating a strong electric field. When the field strength exceeds a certain threshold, it ionizes the gas in the gap, leading to the formation of plasma. This process is efficient and can operate at room temperature, making it suitable for industrial uses.
