Printhead having a thin pre-fired piezoelectric layer |
摘要 |
A printhead having a monolithic semiconductor body with an upper face and a lower face. The body defines a fluid path including a pumping chamber, a nozzle flow path, and a nozzle opening. The nozzle opening is defined in the lower face of the body and the nozzle flow path includes an accelerator region. A piezoelectric actuator is associated with the pumping chamber. The actuator includes a piezoelectric layer having a thickness of about 50 micron or less.
