MINIATURE AEROSOL JET AND AEROSOL JET ARRAY

Title:

MINIATURE AEROSOL JET AND AEROSOL JET ARRAY

Document Type and Number:

WIPO Patent Application WO2006065978

Kind Code:

A3

Abstract:

A miniaturized aerosol jet, or an array of miniaturized aerosol jets for direct printing of various aerosolized materials. In the most commonly used embodiment, an aerosol stream is focused and deposited onto a planar or non-planar target, forming a pattern that is thermally or photochemically processed to achieve physical, optical, and/or electrical properties near that of the corresponding bulk material. The apparatus uses an aerosol jet deposition head to form an annularly propagating jet composed of an outer sheath flow and an inner aerosolladen carrier flow. Miniaturization of the deposition head facilitates the fabrication and operation of arrayed deposition heads, enabling construction and operation of arrays of aerosol jets capable of independent motion and deposition. Arrayed aerosol jets provide an increased deposition rate, arrayed deposition, and multi-material deposition.
