Does anyone know of any manufacturers currently using pizo-electric
ink-jet technology? Many original ink-jet printers used a pizo-crystal
driven "pump" to deliver their charge.  (most current ink jets use
THERMAL ink jet semiconductor devices, which is not desireable.)
The goal is a device which can deliver a very thin jet of fluid, with
minimal despiration. Other systems which can do this are also of
interest. Low cost is not a major factor.
Fuel injection type soloniods may be of interest, but the ones
I'm aware of have too much fanout, and a larger than desired flow.
