Abstract: In some examples, a fluidic conductive trace based radio-frequency identification device may include a flexible substrate layer including a channel, and a trace formed of a conductive fluid that is disposed substantially within the channel. The fluidic conductive trace based radio-frequency identification device may further include a sealing layer disposed on the flexible substrate layer and the trace to seal the conductive fluid in a liquid state within the channel.

Abstract: In an example of a 3D printing method, build material particles are applied to form a layer. Each build material particle includes a metal core and a metal oxide outer shell. The layer is patterned by selectively applying a reactive chemical on at least a portion of the layer to initiate a redox reaction with the metal oxide outer shells of the build material particles in contact with the reactive chemical, which reduces the metal oxide outer shells of the build material particles in contact with the reactive chemical and exposes the metal cores of the build material particles in contact with the reactive chemical. The patterned layer is exposed to rapid thermal processing to sinter the exposed metal cores to form a part layer. Any intact build material particles remain unsintered.

Abstract: In one example in accordance with the present disclosure, a fluid operation cell is described. The fluid operation cell includes a micro-electro-mechanical housing. The housing includes an inlet and an outlet through which fluid flows and electrodes disposed on an interior of the housing to couple to a controller. The fluid operation cell also includes a silicon-based substrate disposed inside, and electrically coupled to, the housing. The substrate includes an on-chip electrical fluid operation component formed thereon. The electrical fluid operation component uses an electrical signal to operate on bypassing fluid. The fluid operation cell includes a dedicated address to be individually activated by the controller.

Abstract: In one example in accordance with the present disclosure, a fluid ejection device is described. The fluid ejection device includes a number of nozzles to eject fluid. Each nozzle includes a firing chamber to hold fluid, a nozzle orifice through which to dispense fluid, and an ejector disposed in the firing chamber to eject fluid through the nozzle orifice. The fluid ejection device also includes a particle detector to detect the presence of foreign particles within the fluid in the firing chamber.

Abstract: In an example implementation, a substance detection method includes sensing for fluid in a chamber of a substance detection device. When fluid is sensed in the chamber, the method includes sensing again for fluid in the chamber. When no fluid is sensed in the chamber, the method includes initiating a substance detection process.

Abstract: Provided in one example is an analyte detection apparatus that includes surface enhanced luminescence (SEL) structure. A dielectric layer underlies the SEL structure. An electric field generating base underlies the dielectric layer. The electric field generating base is to apply an electric field about the SEL structures to attract charged ions to the SEL structures.

Abstract: In one example, an analyte detection package includes a substrate, surface-enhanced luminescence (SEL) structures extending from the substrate and a low wettability housing. The SEL structures have a first wettability for a given liquid. The low wettability housing extends from the substrate to form a chamber between the housing of the substrate about the SEL structures to receive an analyte containing solution. The housing has an inner surface adjacent the chamber, wherein the inner surface has a second wettability for the given liquid less than the first wettability.

Abstract: A fast erasing memristor includes an active region, a resistive heater, and a dielectric sheath. The active region has a switching layer coupled between a first conducting layer and second conducting layer. The resistive heater is coupled to the active region to provide heat to the active region. The dielectric sheath separates the active region and the resistive heater.
