Flow-through liquid ejection using compliant membrane transducer

A method of ejecting a liquid from a liquid dispenser comprising:

• providing the liquid dispenser including:
• a substrate, a first portion of the substrate defining a liquid dispensing channel including an outlet opening, a second portion of the substrate defining an outer boundary of a cavity, and other portions of the substrate defining a liquid supply channel and a liquid return channel;
• a diverter member including:
• a MEMS transducing member, a first portion of the MEMS transducing member being anchored to the substrate, a second portion of the MEMS transducing member extending over at least a portion of the cavity, the second portion of the MEMS transducing member being free to move relative to the cavity;
• and
• a compliant membrane positioned in contact with the MEMS transducing member, a first portion of the compliant membrane covering the MEMS transducing member, and a second portion of the compliant membrane being anchored to the substrate such that the compliant membrane forms a portion of a wall of the liquid dispensing channel, the wall being positioned opposite the outlet opening;
• providing a continuous flow of liquid from a liquid supply through the liquid supply channel through the liquid dispensing channel through the liquid return channel and back to the liquid supply;
• and
• selectively actuating the diverter member to divert a portion of the liquid flowing through the liquid dispensing channel through outlet opening of the liquid dispensing channel.
