Plasmsa patch device for skin disease therapy

Low-temperature plasmas have been applied to cure skin disease. Surface dielectric barrier discharge (SDBD) could be suitable method to make patchable plasma devices for bio-medical applications. In this presentation, we will report on the plasma patch device and the applications for human skin therapy. The plasma patch device was the isolated air discharge system in room temperature. The concentration of reactive oxygen and nitrogen species in the patch device were measured by optical absorption spectroscopy. Main species were reactive oxygen species due to room temperature operation. And, we applied the plasma patch to cure the skin diseases such as psoriasis and atopy. In animal experiment, the skin diseases were cured through recovery of ion channels, and it was confirmed that there was no toxicity when treated for up to 10 minutes a day for a week.
