  • Publication number: 20180021776
    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.

  • Publication number: 20180008979
    Abstract: Fluid may be pumped within a microfluidic channel across a cell/particle sensor using a microscopic resistor. The microscopic resistor may be selectively actuated so as to heat the fluid within the microfluidic channel to a temperature below a nucleation energy of the fluid so as to regulate a temperature of the fluid for at least when the cell/particle sensor is sensing the fluid.

  • Publication number: 20170341076
    Abstract: Example implementations relate to a microfluidics sensing system. For example, a microfluidics sensing system may include a portable computing device to execute a microfluidics application, a microfluidic chip coupled to the portable computing device, the microfluidic chip including a microfluidic pumping and sensing region to perform a test on a biologic sample, and a printed circuit board (PCB) on a microfluidic reader to instruct the microfluidic pumping and sensing region to perform the test based on a command received from the microfluidics application.

  • Patent number: 8657414
    Abstract: A fluid-ejection printhead die includes a fluid-ejection firing element and an electrochemical cell. The fluid-ejection firing element is to cause droplets of fluid to be ejected from the fluid-ejection printhead die. The electrochemical cell is to measure an electrical property of the fluid. The fluid-ejection firing element and the electrochemical cell are both part of the fluid-ejection printhead die.

  • Patent number: 7909424
    Abstract: A method and an apparatus for dispensing liquid are disclosed. The method includes the steps of storing one or more liquids in a thermal inkjet print head and providing a well plate having at least one well. At least one of the liquids is dispensed from the thermal inkjet print head into at least one well. The volume of the dispensed liquid is a fraction of the total required volume of the liquid in the at least one well, and the dispensing step is performed multiple times to dispense the required volume of the at least one liquid in at least one well.
