Floating Electrode DBD Devices

Definition

Floating electrode dielectric barrier discharge (DBD) devices are systems that utilize non-thermal plasma generated between two electrodes, where one of the electrodes is not grounded or is isolated from the electric circuit. This setup allows for the generation of plasma at atmospheric pressure, which has unique properties beneficial for various applications, including the treatment of chronic wounds. The floating electrode creates an electric field that enhances the uniformity and efficiency of the plasma discharge, making it suitable for therapeutic use.
