MICRO-JET NOZZLE ARRAY FOR PRECISE DROPLET METERING AND STEERING HAVING INCREASED DROPLET DEFLECTION

摘要

We present the architecture and fabrication method of a fluidic device with increased droplet deflection. The device is capable of producing picoliter size droplets precisely and steering them. The precision is a consequence of the reproducibility of the nozzles that are made using VLSI technology and tools. In addition, the droplet size is determined by the precise timing of applied heat pulses. We present both experimental and modeling results.
