Abstract

Recent advances in atmospheric pressure plasma research have resulted in applications for many fields such as plasma medicine [1] , flexible hybrid electronics [2] , agriculture, and plasma processing. Recently, a group from NASA showcased a novel application of atmospheric pressure plasma in flexible hybrid electronics (FHE) [3] , [4] . In [3] , [4] , a dielectric barrier discharge (DBD) is used to deposit ink on the flexible substrate and achieves self-sintering. The system also known as plasma jet printer has shown considerable advantages over conventional aerosol-based printing in form of higher conductivity and packing density [3] . The DBD plasma geometry is similar to those used in plasma medicine but has the opposite functionality. The plasma medicine is used for etching and sterilization and the same plasma in FHE is used for deposition and sintering. This paper will demonstrate a 2D model using ESI software CFD-ACE+ for the dielectric barrier discharge and showcase the difference in DBD for use in plasma deposition. The 2D model is simulated under varying input parameters such as applied voltage, pressure, gas flow, and frequency of applied waveform.
