ABSTRACT:
Provided is an inkjet nozzle arrangement which includes a wafer base defining an ink chamber with an ink inlet channel and an ink ejection port. The arrangement also includes an upper electrode plate and a lower electrode plate separated by at least one polytetrafluoroethylene (PTFE) layer within the chamber. The upper plate has a corrugated portion which concertinas upon movement of said top plate, wherein ink is ejected from the ink ejection port through the utilization of attraction and related movement between the plates when a potential difference is applied therebetween.
