Current transformer as power sensor for cold atmospheric plasmas
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. Challenge The simultaneous measurement […]
Efficient generation of plasma-activated aerosols
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. Challenge Plasma-activated water (PAW) is well known for its […]
Plasma electrodes for pulse energy enhancement
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. Challenge Research and development activities show, that dielectric barrier discharge (DBD) cold […]
Plasma toothbrush with an innovative electrode configuration
Plasma toothbrush with an innovative electrode configuration The technology comprises an innovative toothbrush that uses an integrated high-voltage electrode to generate a cold plasma at the bristles, thus combining mechanical cleaning with an antibacterial plasma effect. Challenge Healthy teeth are an important part of overall well-being and contribute to a positive appearance. Plaque, tartar and […]
Multi-phase plasma generator
Multi-phase plasma generator The technology comprises a multi-phase plasma device for efficient generation of a dense and homogeneously distributed cold plasma for cleaning of air and gases. Challenge Clean air and clean gases are of high importance for many industrial applications and processes. The purification of air with plasma can be used for germ inactivation […]
Lice Eraser
Lice Eraser 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, […]
New plasma device to treat hair loss
The prevalence of hair loss (Alopecia) is increasing due changing lifestyle pattern, increased emphasis on appearances among the young population, high level of stress and rising geriatric population. In addition, hair loss cases are rising due to chronic diseases such as Polycystic Ovary Syndrome (PCOS), cancer, or rheumatoid arthritis.
Scientists at the HAWK in Göttingen, Germany developed a new brush-like plasma device for treatment of the scalp to promote hair growth. The device can significantly enhance microcirculation as well as oxygen saturation, which are key parameters for stimulating hair growth.
