Abstract: We present the fabrication, assembly, and packaging of first generation nanoenergetic fluidic jet generators. The generators consist of an energetic material chamber, elastic piston, vaccine reservoir, and convergent nozzle cap all tightly bonded in a self-contained device using micro-electromechanical system (MEMS) processing techniques. Maximum deformation lengths of the polydimethylsiloxane (PDMS) membranes are characterized as a function of PDMS diameter, PDMS thickness, energetic material composition, and energetic material mass using high-speed photography and compared with theoretical calculations. Assembled nanoenergetic fluidic jet generators are analyzed to extract critical operation parameters such as fluidic jet velocity, ejected jet diameter, penetration depth, and fluidic dispersion using in air jet velocity measurements and ballistic gel penetration characterization. Performance scaling laws have been established to determine design parameters for smaller future generation devices.
