Flow-through liquid ejection using compliant membrane transducer

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

• providing a 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 a liquid supply channel and a liquid return channel;
• a diverter member positioned on a wall of the liquid dispensing channel that includes the outlet opening, the diverter member including:
• a MEMS transducing member, a first portion of the MEMS transducing member being anchored to the wall of the liquid dispensing channel that includes the outlet opening, a second portion of the MEMS transducing member extending into a portion of the liquid dispensing channel that is adjacent to the outlet opening, the second portion of the MEMS transducing member being free to move relative to the outlet opening;
• and
• a compliant membrane positioned in contact with the MEMS transducing member, a first portion of the compliant membrane separating the MEMS transducing member from the continuous flow of liquid through the liquid dispensing channel, and a second portion of the compliant membrane being anchored to the wall of the liquid dispensing channel that includes 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.
