Description

technical field [0001] The invention belongs to the technical field of plasma generating devices, and more specifically relates to a portable large-area plasma jet device and system. Background technique [0002] Atmospheric pressure non-equilibrium plasma is a plasma generated under atmospheric pressure, and its electron temperature can be as high as tens of thousands of degrees, while the temperature of ions and neutral particles is much lower than the electron temperature, usually close to room temperature, so the gas temperature during discharge is also close to room temperature . The atmospheric pressure low-temperature plasma jet device can generate plasma jets under atmospheric pressure, without limiting the size of the plasma discharge gap to the object to be processed, and the operation is simple, and the generated gas has low temperature and high activity. [0003] With the wide application of low-temperature plasma in the field of biomedicine, miniaturization and...
