A new breakthrough in science! Chinese scientists develop a new handheld plasma jet which can expand the application field of the low-temperature atmospheric plasma jet.

Recently, researchers of the department of physics and electronics, school of electronic science and engineering in the UESTC have successfully developed a new handheld plasma jet after two years of scientific experiments.

Plasma are excited by microwave energy. By designing a special structure for the interior of the plasma jet and the nozzle, the low-temperature plasma jet can exist stably in the atmosphere without quartz tube and other constrained pipes. The length of the jet is over 2 centimeters, which can greatly expand the application field of the low-temperature atmospheric plasma jet.
