Dielectric Barrier Discharge (DBD)

Dielectric Barrier Discharge (DBD) is a method of generating plasma—an ionized state of matter—by applying a high-voltage electrical field across two electrodes separated by an insulating material called a dielectric. When the voltage is high enough, it causes frequent, short-lived electrical sparks or micro-discharges in the gap, converting the surrounding gas into plasma. DBD is commonly used for ozone production, surface treatment, and sterilization because it efficiently creates plasma at atmospheric pressure without causing damage to materials. It is safe, controllable, and versatile for various industrial and environmental applications.
