Solid-state ink-jet print head

摘要

An ink-jet print head comprises an ink drive unit formed on a first substrate and an ink reservoir unit formed on a second substrate. The ink drive unit includes a thin film piezoelectric transducer formed on one side of the substrate. The reservoir unit includes an etched cavity in the substrate for forming an ink reservoir, the cavity having an aperture in the base extending through the substrate to form an ink nozzle. The ink drive and ink reservoir units are bonded together with the piezoelectric transducer within the ink reservoir. Activating the transducer expels ink from the reservoir via the ink nozzle.
