Our Plasma Pen converts electrical energy which is transmitted to the applicator tip (probe) by impulse. Our device creates an electrical discharge between two electrodes separated by an insulating dielectric barrier. A charge collects on the surface of the barrier and discharges a flash of plasma via our 0.4mm probe – all within millionths of a second. Using a continuous direct energy source, we ionise nitrogen and oxygen in the air to create a plasma gas. This plasma gas is sustained by the unique fingertip and on-demand control of plasma our device offers.
