This abstract first appeared for US patent application 18929244 titled 'LIQUID EJECTING HEAD AND LIQUID EJECTING SYSTEM
Original Abstract Submitted
A liquid ejecting head includes a piezoelectric element in which a first drive electrode, a piezoelectric body, and a second drive electrode are laminated, a humidity detection unit used for detecting a humidity, which includes a first detection electrode, an interposed layer, and a second detection electrode, and a temperature detection unit used for detecting a temperature, which includes a temperature detection resistor. The piezoelectric body is provided between the temperature detection resistor and the humidity detection unit in a direction of lamination in which the first drive electrode, the piezoelectric body, and the second drive electrode are laminated, and at least one of the first detection electrode, the interposed layer, and the second detection electrode is provided at a position to overlap the temperature detection resistor in the direction of lamination.
