Abstract: In a print head having a bimorph thin-film piezo actuator, the piezo-electric actuator is arranged on a membrane at a first side of the piezo-electric actuator and a passive layer is arranged on the piezo-electric actuator at a second side of the piezo-electric actuator, wherein the second side is opposite to the first side. The membrane is more compliant, at least in a lateral direction, for contraction than the passive layer. Thus, a bending direction of the actuator is affected. As a consequence, there is no need for a bias voltage on the actuator during a standby state of the print head. Omitting the bias voltage during standby results in an increased lifetime and stability of the actuator assembly.
