  • Microfluidic ejection element and method of operation of a microfluidic ejection element having a simplified interface
    Patent number: 10857253
    Abstract: A control circuit for a thermally-activated microfluidic ejection element and a method of dispensing a fluid composition from the same is provided. The thermally-activated microfluidic ejection element includes a plurality of nozzles and a thermal actuator associated with each nozzle, and a control circuit that includes: a logic circuit that increments through a pre-determined sequence, wherein the sequence is defined by the physical layout of the thermally-activated microfluidic ejection element; a first input in electrical communication with the logic circuit; a second input in electrical communication with each thermal actuator, wherein the first input and second input are used to select and energize each thermal actuator on the thermally-activated microfluidic ejection element.
