Plasma generators: Compact CeraPlas™ HF element for cold plasma
TDK Corporation (TSE:6762) presents CeraPlas™ HF, a compact cold plasma generator element that is based on a PZT (lead zirconate titanate) ceramic and packaged in a plastic housing. CeraPlas HF measures in at just 47.3 mm x 20 mm x 20 mm and its leads are suitable for soldering. Further notable features are its low weight, low power consumption and low input voltage. CeraPlas HF can be integrated easily and without any special safety measures for protection against high voltage in plasma systems. The new plasma generator is able to ionize different gases – including air – under normal pressure. Because the temperature remains below 50 °C, heat-sensitive materials can be treated with plasma. The combination of compact dimensions and low power consumption therefore makes CeraPlas technology ideal for battery-powered handheld devices.
CeraPlas has a wide variety of applications. It can be used for the surface treatment of plastics, for example, to make them easier to print or write on. Another area of applications is the disinfection of wounds or the sterilization of devices or foods. Moreover, the generation of ozone also enables unpleasant odors to be eliminated.
Apart from the generator itself, TDK also offers an evaluation kit, which, in addition to a CeraPlas HF element, also contains control electronics that enables the plasma generator to be operated at different performance levels.
Laboratory samples of the CeraPlas HF element are available under ordering code Z63000Z2910Z 1Z60. The order code for the evaluation kit – including the control electronics – is Z63000Z2910Z 1Z61. This kit is recommended for initial tests, as it enables the CeraPlas element to be operated without any problems.
