Abstract: A system may comprise a voltage upconverter, a universal serial bus (USB) connector to receive an input voltage from a USB port on a computing device, and a microfluidic diagnostic chip communication link to electrically couple the voltage upconverter to a microfluidic diagnostic chip wherein the voltage upconverter is to convert the input voltage to be received by the USB connector to an output voltage sufficient to drive a pump on the microfluidic diagnostic chip. A diagnostic system may comprise a microfluidic diagnostic chip comprising a pump and a voltage upconverter to receive an input voltage from a universal serial bus (USB) port of a computing device and to convert the input voltage into an output voltage that powers activation of the pump.

Abstract: A method of microfluidic detection can include detecting, using an impedance sensor, an impedance of a fluid to indicate whether a threshold amount of fluid has been received in a reservoir of a microfluidic chip. The method can include initiating a test performed by the microfluidic chip on the received fluid when the threshold amount of fluid has been received.

Abstract: A printhead includes a plurality of firing chambers, a plurality of fluid ejectors, and at least one field generating member. Each one of the firing chambers includes a nozzle region to receive printing fluid. The printing fluid includes an ink vehicle having pigments disposed therein. At least one field generating member generates a non-uniform electric field to apply forces to maintain respective pigments in the ink vehicle of the printing fluid in the nozzle region.

Abstract: A diagnostic cassette includes a substrate, to physically and electrically connect the product to a computing device, a reservoir defined within the substrate to receive a fluid sample for processing by the diagnostic cassette, a reagent to react with the fluid sample deposited in the reservoir to form a solution to enable processing of the fluid sample by the diagnostic cassette, a channel to direct the solution, and a sensor to measure a number of parameters of the solution passing through the channel. A method for measuring microfluidic samples includes receiving, in a reservoir, a fluid sample to be measured, combining the fluid sample with a reagent to create a solution, moving the solution through a channel, and measuring the solution, using sensors, as the solution passes through the channel.
