Abstract: A microfluidic pressure sensor may include a reference chamber, a sensed volume, a microfluidic channel connecting an interior of the reference chamber to an interior of the sensed volume, a volume of liquid contained and movable within the microfluidic channel while occluding the microfluidic channel and a sensor to output signals indicating positioning of the volume of liquid along the microfluidic channel. Positioning of the volume of liquid along microfluidic channel indicates a pressure of the sensed volume.

Abstract: A micro light-emitting diode (LED) display assembly includes a backplane, a passivation layer on the backplane, a micro LED on the passivation layer, and a non-transparent metal housing on the passivation layer. The housing includes a base portion on the passivation layer, a sidewall portion upwardly extending from the base portion, a cap portion connected at a top of the sidewall portion, an orifice in the cap portion, and a notch in the cap portion and adjacent to the orifice. The assembly also includes a translucent filter positioned in the notch and covering the orifice, and a pocket defined by an enclosed area in between the sidewall portion, the cap portion, the filter, and the passivation layer. The micro LED is encased within the pocket such that light transmitted from the micro LED directly hits and passes through the filter.

Abstract: Examples disclosed herein relate to a layered RFID tag. In one implementation, a layered passive chipless RFID tag includes a first conductive layer, a second dielectric layer, and a third conductive layer. The first, second, and third layers may be in a stacked configuration with the second layer between the first layer and the second layer.

Abstract: In some examples, a method of sensing an ink level includes applying a pre-charge voltage to a sense capacitor to charge the sense capacitor with a charge, sharing the charge between the sense capacitor and a reference capacitor, causing a reference voltage at a gate of an evaluation transistor, and determining a resistance from a drain to a source of the evaluation transistor that results from the reference voltage.

Abstract: A micro-structure transfer system may include a printhead and a pressure control device to control a pressure of fluid coupled with the printhead. The pressure control device forms a meniscus of fluid at a number of nozzles defined within the printhead to pick up a number of micro-structures. A printhead for transferring micro-structures includes a number of fluid chambers, a number of nozzles defined in an orifice plate through which fluid may exit the chambers, and a pressure control device to control a pressure of fluid within each of the chambers. The pressure control device forms a meniscus of the fluid at a number of nozzles defined within the printhead to pick up a number of micro-structures.
