Current transformer as power sensor for cold atmospheric plasmas
This technology allows to measure plasma voltage and plasma current simultaneously and with a combined device in the high-voltage circuit of a cold atmospheric plasma. From this, the discharge power of the plasma can subsequently be calculated. The new measuring device is compact and a cost-effective alternative to the measuring technology normally required.
The present invention suggests a novel device and method for the plasma-based devulcanization of vulcanized rubber, which can be reused as raw material for the fabrication of vulcanizable rubber particles.
The PLASMA-ROLLER allowes to desinfect surfaces and/or activate surfaces for coating. A great variety of materials can be residue-free treated without using chemicals.
Unique nano-seals allow for forgery-proof object identification. Due to a combination of ion irradiation and simultaneous co-deposition of metal atoms a unique surface pattern is created. Its manufacturing process and size of a few square micrometers make it impossible to be reproduced, thus creating a forgery-proof identifier.
Flexible plasma electrode design for effective treatment of irregular surfaces
Surface activation or cleaning by cold plasma treatment is getting more and more attention. Current plasma based solutions have mostly fixed electrodes, which are only suited for planar surfaces. Scientists at the HAWK developed a plasma device with flexible electrodes, which allow treatment of irregular surfaces.
Plasma device for tapes and other flexible materials
Surface activation or cleaning by cold plasma is getting more and more attention. Current plasma-based solutions for flexible materials however lack efficiency or are technically too complex and error-prone. Scientists at the HAWK developed a plasma roller device for effective and fast plasma treatment of flexible materials.
Here we present a hand dryer applying simultaneously an atmospheric-pressure plasma which reduces the amount of germs on the hand surface and in the ambient air significantly.
LICE ERASER — reliably killing of head-lice and their nits
The LICE-ERASER kills the head-lice and their nits reliably and without any side effects. To use, the LICE-ERASER has to be moved through the hair like a hair-brush. The LICE-ERASER produces a cold plasma generated between the comb tooths, which kills the head-lice and their nits. This procedure is completely free of pain, the user will not feel anything.
New plasma device for chemical-free cleaning and sanitizing of textiles
Scientists at the HAWK in Göttingen, Germany developed a new plasma device for chemical-free cleaning and sanitizing of textiles or clothes. In addition, odors can also be greatly reduced or eliminated. The device consists of two rollers coated with a flexible dielectric material, which serve as electrodes for plasma treatment.
Scientists at the HAWK in Göttingen, Germany developed a new brush-like plasma device for chemical-free treatment of the scalp to promote hair growth. The small device is easy to handle and can significantly enhance microcirculation as well as oxygen saturation, which are key parameters for stimulating hair growth.
