摘要： A thermal fluid-ejection mechanism includes a substrate having a top surface. A cavity formed within the substrate has one or more sidewalls and a floor. The angle of the sidewalls from the floor is greater than or equal to nominally ninety degrees. The thermal fluid-ejection mechanism includes a patterned conductive layer on one or more of the substrate's top surface and the cavity's sidewalls. The thermal fluid-ejection mechanism includes a patterned resistive layer on the sidewalls of the cavity. The patterned resistive layer is located over the patterned conductive layer where the patterned conductive layer is formed on the sidewalls of the cavity. The patterned resistive layer is formed as a heating resistor of the thermal-fluid ejection mechanism. The conductive layer is formed as a conductor of the thermal-fluid ejection mechanism, to permit electrical activation of the heating resistor to cause fluid to be ejected from the thermal fluid-ejection mechanism.

摘要： A fluid ejection assembly includes a fluid slot formed in a first substrate and a channel formed in a chamber layer disposed on top of a second substrate. The bottom surface of the second substrate is adhered to the top surface of the first substrate and fluid feed holes are formed between the fluid slot and the channel. A fluid ejection element is at a first end of the channel and a pump element is at a second end of the channel to circulate fluid horizontally through the channel and vertically through the fluid feed holes.

摘要： In one embodiment, a microfluidic system includes a fluidic channel coupled at each end to a reservoir. A fluid actuator is located asymmetrically within the channel to create a long side and a short side of the channel and to generate a wave propagating toward each end of the channel, producing a unidirectional net fluid flow. A controller is to selectively activate the fluid actuator to control the unidirectional net fluid flow through the channel.

摘要： In one embodiment, a polymerase chain reaction (PCR) system includes a mixture chamber, a denature chamber, an annealing chamber, an extension chamber, and a product chamber, that are fluidically coupled to one another through a plurality of microfluidic channels. An inertial pump is associated with each microfluidic channel, and each inertial pump includes a fluid actuator integrated asymmetrically within its associated microfluidic channel. The fluid actuators are capable of selective activation to circulate fluid between the chambers in a controlled cycle.

摘要： In one embodiment, a fluid ejector structure includes: a chamber; a bridge spanning at least part of the chamber; a channel through which fluid may enter the chamber; a fluid ejector element on the bridge; and an outlet through which fluid may be ejected from the chamber at the urging of the fluid ejector element. The outlet is disposed opposite the fluid ejector element across a depth of the chamber and the chamber, ejector element and outlet are configured with respect to one another such that substantially all of the fluid in the chamber is ejected through the outlet upon actuation of the ejector element.
