Printer head using a radio frequency micro-electromechanical system (RF MEMS) sprayer

摘要

A liquid chamber (28) supplies the liquid to an inner pressure chamber (27) through a liquid inlet (21). The inlet and a liquid outlet (30) extend through the chamber (27) while a cavity resonator (20) surrounds the chamber (27), so that the liquid from the chamber (27) is ejected outwards through the outlet when the inner pressure of the chamber (27) is increased by the resonator.
