|This is just for the piezo unit, yes?
Only for the piezo, two pieces.

|Have you sourced the etched Si nozzle?
Not yet
|I am sure the nozzle could be made at home, no prob.
I'll try with flame narrowing the pipette's end.

|The Glass-Si bond might be tricky.

|Or are you using the Stanford device inkjet as a bassis for your own design?
Yes. The idea is to fill the pipette with Staedler ink and, when
pulse energized, the piezo will constrict
(I hope it will do that, it was hard to communicate technically with
the Chinese vendor) and the pressure will go up and down in the pipette.
Up is the resistance of the weight of the ink column and down is a
hole, so it will spit little ink out.
If not, $15 is not a fortune.

Good work! Keep us in the loop as to your experience with the Chinese vendor.
