Device for precision positioning of low temperature plasma sources

In recent years, the application of low-temperature plasma in biomedical and agricultural research has attracted significant interest due to the plasma’s ability to effectively sterilize, modify surfaces, and generate reactive oxygen and nitrogen species. Accurate positioning of plasma sources and characterization of source operating modes are primary tasks when implemented in real practice. This paper presents a universal device for positioning of plasma sources and measuring equipment. The device is manufactured by FDM 3D printing and has a relatively high structural strength in the absence of metal-containing elements. The developed device allows the active elements of plasma sources to be positioned with high accuracy over objects of various sizes and compositions, and also allows the implementation of sensitive methods for diagnosing plasma characteristics and parameters of processed objects.
