The invention provides for a nozzle apparatus for an inkjet printhead. The
apparatus includes a wafer substrate defining a nozzle chamber and a
nozzle outlet port. The apparatus also includes an electromagnetic piston
inside the chamber, the piston mounted to the wafer substrate via torsion
springs, said piston operatively forced towards the outlet port when
activated. Also included is a solenoid coil positioned on the wafer
substrate about the piston to activate the piston when a current is
passed through the coil.
