Abstract: An inkjet device includes a pumping chamber bounded by a wall, a piezoelectric layer disposed above the pumping chamber, a ring electrode having an annular lower portion disposed on the piezoelectric layer. A moisture barrier layer covers a remainder of the piezoelectric layer over the pumping chamber that is not covered by the annular lower portion of the ring electrode.
