Effective plasma handheld device for manual use
Piezo plasma 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 temperature of less than 50°C. Plasma is used to increase the surface energy of many materials with high efficiency, as well as to reduce germs and odors.

Modules
Different surfaces have to be activated with the appropriate accessories to achieve an ideal result. Currently two different modules are available for the piezo plasma handheld device. The PDD technology used to generate the cold plasma in piezo plasma 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.
Module Standard
This module is designed for the surface treatment of non-conductive substrates such as plastics, ceramics or glass. For effective treatment, a module-to-substrate distance of 1 to 5 mm is recommended. If uncontrolled arcing occurs on the substrate during use, the device switches off automatically. In this case the surface is at least partially conductive and should therefore be treated with the module Nearfield.
Module Nearfield
This module is used to treat (partially) electrically conductive materials such as metals, CFRP, indium tin oxide or conductive plastics. However, this module may also be necessary for the ideal treatment of materials with conductive coatings or assemblies with conductive components. With this module, the plasma only ignites when it is close enough to a conductive surface (this may also be hidden under a thin insulating layer). At a distance of a few millimeters, a violet glow is visible in the gap between module and substrate indicating that the treatment is being performed.
The device automatically detects which module is currently in the device and automatically adjusts the parameters accordingly.
Display
For process control of plasma treatment, the piezo plasma 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
