Effective plasma handheld device for manual use
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.

Different surfaces have to be activated with the appropriate accessories to achieve an ideal result. Currently five different modules are available for the piezobrush® PZ3 plasma handheld device. The PDD technology used to generate the cold plasma in piezobrush® PZ3 is based on the discharge of high electric fields. Therefore, the electrical conductivity of the component to be treated is of decisive importance when choosing the modules.
You can find the different modules here.
For process control of plasma treatment, the piezobrush® PZ3 is equipped with various features that can be selected and modified via the display.
- Process control
◊ Stopwatch: For monitoring the treatment time
◊ Countdown: Time setting with automatic switch-off function
◊ Metronome: Acoustic feedback after defined treatment time
- Power adjustment: Reduction of plasma power in several increments
Stand for the piezobrush® PZ3
The stand has been designed for the piezobrush® PZ3 to allow hands-free operation of the handheld device. The height and angle of the stand can be easily and quickly adjusted according to customer requirements. The rubber studs on the base of the stand ensure a secure footing.
Accurate and reproducible processing of substrates is possible with the stand. The included support plate enables the treatment of conductive and non-conductive substrates.
The stand consists of a frame, a clamping device for holding the PZ3 and a lay-on plate. The stand and its components can be stored in the supplied case.

Technology – Plasma handheld with Piezo Technology
In order to provide products having convincingly compact dimensions, we developed the PDD® Technology. PDD stands for piezoelectric Direct Discharge. It is based on the direct, electric discharge at an openly operated piezoelectric transformer (PT).
By means of PDD® Technology, low input voltage is transformed. This results in high electric field strengths. The ambient process gas – typically air – is dissociated and ionized.
The advantages of direct discharge control are obvious: The excitation of gas molecules is highly efficient and safe. Furthermore, the power density of the compact device is extremely high. In practice, a processing performance level is now achieved that had previously been possible only by means of considerably larger installations. This is the ideal device for manual applications in laboratories, medical technology, in commerce and in industry.
The piezobrush® has been conceived for application by end-users. Here, relyon plasma has paid particular attention to usability and user-friendliness. The piezobrush® requires no specialist, technical knowledge and no complex infrastructure.
The CeraPlas F plasma generator, from TDK Electronics, is a direct high-voltage discharge component for plasma generation, forms the heart of the plasma handheld. The piezoelectric RF plasma generator offers a high ionization rate and an effective ozone generation rate as well as multigas ignition, low power consumption and no magnetic fields.
