Abstract: A method of operating a microfluidic device may include activating a fluid ejection actuator to eject an amount of fluid from a fluid ejection chamber through a nozzle, and activating a pump located within a micro-fluidic channel fluidically coupled to the fluid ejection actuator during a fluid ejection event to create a positive net flow from the pump to the fluid ejection chamber. The fluid ejection event may include a plurality of ejections of fluid from the nozzle.

Abstract: The viscosity of a fluid may be determined using a flow rate determination. The flow rate may be determined based on fluid presence determinations within a capillary channel. Also, a temperature of an environment surrounding a capillary channel may be determined and signals may be transmitted to a thermal element responsive to the determined temperature.

Abstract: A device includes a microfluidic channel structure on a substrate and a first resistive structure on the substrate to control the temperature of at least the substrate. The first resistive structure is separate from, and independent of the, microfluidic channel structure. In some instances, the device includes a second resistive structure.

Abstract: A device includes a microfluidic channel structure on a substrate with a first fluid actuator and a second fluid actuator within the microfluidic channel structure. One of the fluid actuators is selectively employable to at least partially reverse fluid flow within at least a portion of the microfluidic channel structure in response to a blockage or to prevent a blockage.

Abstract: A device including a microfluidic channel structure formed on a substrate and including a first channel and a fluid actuator within the microfluidic channel structure. A sense region within the first channel is to receive a fluid flow of target biologic particles for counting in a single file pattern, with the sense region having a volume on a same order of magnitude as a volume of a single one of the target biologic particles.

Abstract: Examples herein provide a method. The method includes applying an electrical potential difference over a blood sample in a testing cassette of a microfluidic device, the cassette including a microfluidic channel through which the blood sample flows. The method includes measuring, over a duration of time, an electrical signal passing through the blood sample as the blood sample flows from a first end and coagulates at a second end of the microfluidic channel to obtain a measurement function as a function of time. The method also includes correlating the measurement function to a characteristic of the blood sample.
