Plasma electrodes for pulse energy enhancement
A technology for the generation of a non-thermal plasma with enhanced pulse energy is presented. Electrodes are tailored with charge collecting elements, which trigger enhanced pulse energies in plasma filaments and a targeted formation of filamented discharges.
Efficient generation of plasma-activated aerosols
Solutions for an efficient generation of plasma-activated aerosols with high activities are suggested. A cold plasma is ignited directly in the presence of sprayed liquid droplets, leading to intercalation of reactive species on the surface or in the volume of droplets.
Current transformer as power sensor for cold atmospheric plasmas
This compact and cost-effective technology facilitates a real-time, simultaneous measurement of plasma voltage and plasma current with a combined device in the high-voltage circuit of a cold atmospheric plasma. The system exhibits a good time resolution and enables a live plasma self-regulation.
Devulcanization of vulcanized rubber products
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.
PLASMA-ROLLER for conditioning of surfaces
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.
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.
Plasma hand dryer
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.
New plasma device to treat hair loss
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.
