Description

technical field [0001] The invention belongs to the technical field of plasma generating devices, and more particularly, 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 and low temperature plasma jet device can generate plasma jet under atmospheric pressure, and the object to be processed will not be limited by the size of the plasma discharge gap, and the operation is simple, and the temperature of the generated gas is low and the activity is high. [0003] With the wide application of low-temperature plasma in the field of biomedic...
