Abstract: A network of microfluidic channels may include at least three loops interconnected at a junction. Each of the loops may include a fluid channel having a length extending from the junction to a second end; and a fluid actuator along the fluid channel and located at a first distance from junction along the length of the fluid channel and at a second distance less than the first distance from the second end. Activation of the fluid actuator of selected ones of the at least three loops may selectively produce net fluid flow in different directions about the loops. In one implementation, a fluid channel having a fluid actuator may have a bridging portion that extends over another fluid channel.

Abstract: In an example implementation, a method of cell lysis includes moving cell fluid from a first reservoir through a microfluidic channel toward a second reservoir, activating a lysing element multiple times as a cell from the cell fluid passes through the microfluidic channel, and moving lysate fluid that results from the activating through the microfluidic channel and into the second reservoir.

Abstract: Example fluidic channels for microfluidic devices are disclosed. In examples disclosed herein, an example microfluidic device includes a body having a microfluidic network. The microfluidic network includes a main fluid channel to transport a biological fluid from a first cavity of the microfluidic network to a second cavity of the microfluidic network. An auxiliary fluid channel is in fluid communication with to the main fluid channel. The auxiliary fluid channel has a first end and a second end. The first end is in fluid communication with the main fluid channel and the second end is spaced from the main fluid channel. A fluid actuator is positioned in the auxiliary fluid channel to induce fluid flow in the main fluid channel.

Abstract: An inkjet printhead includes an inkjet nozzle with a main actuator and at least one peripheral actuator in the same firing chamber. A determination is made as to whether the inkjet nozzle has sat idle, e.g., not firing for a threshold period of time. When the inkjet nozzle has sat idle, both the main actuator and the peripheral actuator are activated to jet at least one ink drop to renew the inkjet nozzle to mitigate decap conditions. When the inkjet nozzle has not sat idle, only the main actuator is activated to jet ink drops.

Abstract: A fluid recirculation channel for dispensing a plurality of fluid drop weights includes a number of sub-channels. The sub-channels include at least one pump channel, and a plurality of drop generator channels fluidically coupled to the at least one pump channel. The fluid recirculation channel further includes a number of pump generators incorporated into the at least one pump channel, a number of drop generators incorporated into drop generator channels, and a plurality of nozzles defined within the drop generator channels, the nozzles being at least as numerous as the number of drop generators.

Abstract: In one example in accordance with the present disclosure, a fluid analysis device is described. The device includes a substrate, a die adhered to the substrate, and at least one fluid analysis element disposed on the die. A lid is adhered to the substrate and includes a channel formed thereinto be seated over the die. The device also includes an inlet port to the channel and an outlet from the channel. The inlet port and the outlet port are formed on at least one of the substrate and the lid. A number of electrical traces couple the die to a controller.

Abstract: In an example implementation, a method of microfluidic filtering includes activating a first fluid pump within a microfluidic channel to cause a forward flow of fluid through the microfluidic channel and through a filter of a filter loop. The filter loop intersects the microfluidic channel at a loop entry and at a loop exit. The method includes activating a second fluid pump to cause a reverse flow of fluid through the filter.
