Abstract: In an example implementation, a conductive trace printing system includes a conductive trace application station to apply a conductive trace onto a media substrate. The printing system also includes a conductive trace enhancement station to expose the conductive trace to an electroless metal plating solution to generate an enhanced conductive trace.

Abstract: A display may include a substrate, an array of thin film transistors, an array of micro-light-emitting diode elements supported by the substrate and an array of sensing elements supported by the substrate. Each sensing element may include a continuous conductive layer functioning as part of the sensing element and extending along the substrate as an electrically conductive trace connected to one of the thin film transistors.

Abstract: One example of a device includes an antenna, a memristor code comparator, and a controller. The antenna is to receive a wake up signal. The memristor code comparator is to compare the wake up signal to a reference signal. The controller is to provide a trigger signal to wake up the device in response to the wake up signal matching the reference signal.

Abstract: In some examples, a micro light-emitting diode (μLED) panel may include a μLED including at least two electrodes (or bond pads), and a ferromagnetic material included in the at least two electrodes (or bond pads) and/or disposed on the at least two electrodes (or bond pads). The μLED panel may further include a panel substrate including ferromagnetic material selectively disposed at least at two locations corresponding to locations of the at least two electrodes (or bond pads) to align a plurality of μLEDs including the μLED onto the panel substrate.

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 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.
