摘要： A fluid injection module may include a fluid ejection die, a die carrier, a bypass fluid passage in at least one pressure regulator. The fluid ejection die may include nozzle orifices on a front face of the die, first and second fluid passages extending through the die and a microchannel extending from the first fluid passage to the second fluid passage proximate the nozzle orifices to circulate fluid from the first fluid passage to the second fluid passage. Third and fourth fluid passages may extend through the die carrier. The bypass fluid passage may extend from the third fluid passage to the fourth fluid passage while being connected to the first fluid passage and the second fluid passage. The at least one pressure regulator is to induce pressure differential driven fluid flow across the microchannel and across the bypass fluid passage.

摘要： In one example in accordance with the present disclosure, a fluid analysis device is described. The fluid analysis device includes a chamber to receive a number of fluids. At least one fluid includes an electrochemical label with a unique electrochemical response to an applied electrical potential. A multi-electrode sensor of the fluid analysis device is disposed within the chamber and detects electrical signals within the chamber. The fluid analysis device also includes a controller coupled to the multi-electrode sensor. The controller applies an electrical potential across multiple electrodes of the multi-electrode sensor and identifies, from the electrical signal detected by the multi-electrode sensor, fluids currently in the chamber based on the unique electrochemical responses of associated electrochemical labels.

摘要： An example overfill-tolerant microfluidic structure can include an inlet microfluidic channel. A sample chamber can be connected to the inlet microfluidic channel to receive liquid from the inlet microfluidic channel. A gas-permeable liquid barrier can be connected to the sample chamber and positioned to allow gas to flow out of the sample chamber. An overflow chamber can be connected to the inlet microfluidic channel. A capillary break can be positioned between the inlet microfluidic channel and the overflow chamber. The capillary break can include a narrowed opening with a smaller width than a width of the inlet microfluidic channel. In some examples, the gas-permeable liquid barrier can allow gas to flow out of the sample chamber at a pressure lower than the break pressure, and prevent liquid from flowing out of the sample chamber at the break pressure.

摘要： In one example in accordance with the present disclosure, a fluid manipulation system is described. The fluid manipulation system includes a microfluidic channel through which fluid is to flow. The fluid includes biomolecules to be separated. The fluid manipulation system also includes at least one array of biomolecule-capturing pillars disposed within the microfluidic channel to capture biomolecules from the fluid. Barriers rise from a surface of the microfluidic channel. The barriers span a width of the microfluidic channel orthogonal to a flow of the fluid to induce vortices in the fluid flow.

摘要： In one example in accordance with the present disclosure, a fluid manipulation system is described. The fluid manipulation system includes a microfluidic channel through which fluid is to flow. The fluid includes particles to be separated. The fluid manipulation system includes a first electrode pair on a first side of the microfluidic channel. The first electrode pair includes a top electrode formed on a lid of the microfluidic channel and a bottom electrode formed on a floor of the microfluidic channel. The fluid manipulation system also includes a second electrode pair on a second side of the microfluidic channel. The second electrode pair also includes a top electrode and a bottom electrode. The electrode pairs are to generate an alternating electrical field across the microfluidic channel.

摘要： A print module includes a printhead die, an input regulator to regulate input fluid pressure to the die, and an output regulator to regulate output fluid pressure from the die. A method includes receiving fluid at an input regulator to a print module, creating a fluid pressure differential within the print module between the input regulator and an output regulator, flowing fluid from the input regulator through a printhead die and to an output regulator using the pressure differential, and drawing fluid from the output regulator.

摘要： A fluid injection module may include a fluid ejection die, a die carrier, a bypass fluid passage in at least one pressure regulator. The fluid ejection die may include nozzle orifices on a front face of the die, first and second fluid passages extending through the die and a microchannel extending from the first fluid passage to the second fluid passage proximate the nozzle orifices to circulate fluid from the first fluid passage to the second fluid passage. Third and fourth fluid passages may extend through the die carrier. The bypass fluid passage may extend from the third fluid passage to the fourth fluid passage while being connected to the first fluid passage and the second fluid passage. The at least one pressure regulator is to induce pressure differential driven fluid flow across the microchannel and across the bypass fluid passage.
