Abstract

We present a novel CMOS/MEMS microfluidic device that enables the controlled production and redirection of streams of picoliter-sized droplets at frequency rates in the hundreds of kilohertz range. Droplet generation and jet manipulation are achieved using voltage-controlled thermal modulation, at modest temperatures and with no moving elements. We discuss the fabrication and operating physics of the device and we compare experimental performance data with 3D CFD simulations. We discuss applications of this device to continuous inkjet printing.
