More Information
Summary:An apparatus includes a reservoir and a printhead. The printhead includes a support structure including a deformable portion defining at least a top surface of a pumping chamber, a flow path extendingfrom the reservoir to the pumping chamber to transfer fluid from the reservoir to the pumping chamber, and an actuator disposed on the deformable portion of the support structure. A trench is definedin a top surface of the actuator. Application of a voltage to the actuator causes the actuator to deform along the trench, thereby causing deformation of the deformable portion of the support structure to eject a drop of fluid from the pumping chamber. 一种设备，包括储存器和打印头。打印头包括支撑结构，其包括可变形部分，可变形部分至少限定泵送腔的顶部表面；流动路径，其从储存器延伸到泵送室，用于将流体从储存器输送到泵送室；以及致动器，其设置在支撑结构的可变形部分上。沟槽限定在致动器的顶部表面中。向致动器施加电压引起致动器沿着所述沟槽变形，从而引起支撑结构的可变形部分变形，以便从泵送室喷射流体液滴。
