摘要： A fluid ejection device includes a fluid slot, at least one fluid ejection chamber communicated with the fluid slot, a drop ejecting element within the at least one fluid ejection chamber, a fluid circulation channel communicated with the fluid slot and the at least one fluid ejection chamber, and a fluid circulating element communicated with the fluid circulation channel. The fluid circulating element is to provide on-demand circulation of fluid from the fluid slot through the fluid circulation channel and the at least one fluid ejection chamber.

摘要： An apparatus includes a microfluidic channel and a flow sensor along the microfluidic channel. The flow sensor includes a heat emitting resistor for connection to an electric current source, analytical parameter sensor and electronics. The heat emitting resistor has a resistance that varies in response to temperature. The electrical parameter sensor is to sense an electrical parameter of the heat emitting resistor that is based on the resistance of the heat emitting resistor. The electronics determine a flow based on the sensed electrical parameter.

摘要： A fluid ejection device includes a fluid slot, two laterally adjacent fluid ejection chambers each communicated with the fluid slot and having a drop ejecting element therein, and a fluid circulation path communicated with each of the two laterally adjacent fluid ejection chambers and having a fluid circulating element therein, with the two laterally adjacent fluid ejection chambers to concurrently eject drops of fluid therefrom such that the drops of fluid are to coalesce during flight.

摘要： A fluid ejection device includes a fluid ejection chamber having a drop ejecting element therein, a first fluid channel to communicate a first fluid with the fluid ejection chamber, a second fluid channel to communicate a second fluid different than the first fluid with the fluid ejection chamber, and a fluid pump communicated with one of the first fluid channel and the second fluid channel. As such, the fluid ejection chamber is to selectively eject drops of the first fluid, the second fluid, and a combination of the first fluid and the second fluid therefrom.

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 microfluidic mixing device includes a mixing channel, a fluid inlet chamber to pass fluids into the mixing channel, an axis-asymmetric mixing actuator integrated within the channel to cause fluid displacements that mix the fluids as they flow through the channel, and an outlet chamber to receive the mixed fluids.

摘要： A fluid exit passage is at a location along a microfluidic channel. A fluid displacement device is proximate the location along the microfluidic channel. A constituent locator distinguishes a target constituent in a fluid within the microfluidic channel from remaining non-target constituents and locate the target constituent proximate the fluid exit passage. A controller selectively actuates the fluid displacement device when the target constituent is proximate the fluid exit passage to discharge the target constituent from the microfluidic channel through the fluid exit passage.
