ABSTRACT:
A microelectromechanical fluid ejection device, comprising a mechanical actuator (28), an outer arm portion (31) and an inner arm portion (32), the actuator (28) being displaceable upon receipt of an electrical current in the inner arm portion (32), the outer arm portion (31) electrically isolated from the inner arm portion (32), said displacement causing ejection of fluid from an aperture (26) in the device, and, drive circuitry for supplying the electrical current to the inner arm portion (32).
