Abstract
Methods for generating one or more atmospheric pressure plasma jets that can be used to deposit various types of conductive traces, coatings, and micro/nano-sized particles/structures on two or three dimensional body surfaces. The method includes generating atmospheric pressure plasma, nebulizing a precursor to generate an aerosol; receiving the aerosol from the nebulizer in a chamber; mixing the atmospheric pressure plasma with the aerosol from the chamber at a nozzle; and printing the plasma-exposed aerosol onto the surface of a substrate.
