Abstract
A piezoelectric device and method of manufacturing the same and an inkjet head are described. In one embodiment, the inkjet print head comprises a plurality of jets, wherein each of the plurality of jets comprises a nozzle, a pressure chamber connected with the nozzle, a piezoelectric body coupled to the pressure chamber, and an electrode coupled to the piezoelectric body to cause displacement of the piezoelectric body to apply pressure to the pressure chamber in response to a voltage applied to the electrode; and wherein electrodes of two or more of the plurality of jets have different sizes to cause their associated piezoelectric bodies to have a uniform displacement amount when the voltage is applied to the electrodes.
