ABSTRACT:
A fluid ejection chip includes a substrate. A plurality of nozzle arrangements is positioned on the substrate. Each nozzle arrangement includes a nozzle chamber defining structure which defines a nozzle chamber and which includes a wall in which a fluid ejection port is defined. Each nozzle arrangement includes at least one actuator for ejecting fluid from the nozzle chamber through the fluid ejection port. The, or each, actuator is displaceable with respect to the substrate on receipt of an electrical signal. The, or each, actuator is formed in said wall of the nozzle chamber defining structure, so that displacement of the, or each, actuator results in a change in volume of the nozzle chamber so that fluid is ejected from the fluid ejection port.
