Novel Silicon-Based Continuous Inkjet Printhead Employing Asymmetric Heating Deflection Means
  DOI :  10.2352/ISSN.2169-4451.2001.17.1.art00063_1  Published OnlineJanuary 2001

In this paper, a novel continuous inkjet technology will be presented. The technology presented uses a pulsed application of asymmetric heat to a pressurized stream of ink emitted from a nozzle both to break up the stream into regularly sized printing drops and to deflect the drops onto a receiver while allowing the non-printing drops to be captured. Depending on the nozzle geometry, fluid properties and applied pressure arrays of small drop volumes (3 picoliters) can be jetted and deflected at high velocity (10 m/s). The printhead, fabricated in silicon, is produced by MEMS processing techniques that are CMOS compatible, allowing for direct integration of circuitry. The basic device geometry and operation will be described including some experimental results.
