Integrated Thermal Modulation and Deflection of Viscous Microjets with Applications to Continuous Inkjet Printing

Furlani E.P., Ng K.C., Lopez A.G., Anagnostopoulos C., Eastman Kodak, US

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. This device consists of a pressurized reservoir [...]

Numerical Analysis of Nonlinear Deformation and Breakup of Slender Microjets with Application to Continuous Inkjet Printing

Furlani E.P., Eastman Kodak Company, US

Liquid microjets are inherently unstable and can be modulated in a controlled fashion to create steady streams of picoliter-sized droplets at frequency rates in the hundreds of kilohertz. Such modulation has been achieved using CMOS/MEMS [...]
