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: 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 an example implementation, a touch-sensitive illuminating display includes a transparent flexible touch layer, a transparent top conductive layer adjacent the flexible touch layer, a bottom conductive layer, and an electroluminescent layer and variable-thickness dielectric layer sandwiched between the top and bottom conductive layers. Pressure against the flexible touch layer is to reduce the dielectric layer thickness and bring the top and bottom conductive layers closer together, causing the electroluminescent layer to emit light where the pressure is applied.

Abstract: An annealing device may include an array of thermal heaters, each thermal heater comprising a resistive element formed into a cavity and wherein each of the thermal heaters within the array of thermal heaters are selectively activated to anneal an annealable material deposited into the cavities.

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.
