PiezoBrush PZ3 has been designed as a compact plasma handheld device for use in laboratories, predevelopment and assembly of small series. With a maximum power consumption of 18 W, the Piezoelectric Direct Discharge (PDD) technology is used to generate cold active plasma at a low temperature. The heart of this portable plasma device is the TDK piezo plasma generator CeraPlas – a high-voltage discharge device for generating cold atmospheric-pressure plasma. Plasma is used to increase the surface energy of many materials with high efficiency, as well as to reduce germs and odors.
