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, an additive manufacturing system is described. The additive manufacturing system includes an additive manufacturing device to form a three-dimensional (3D) printed object. The additive manufacturing system also includes a controller to form a 3D printed capacitor on a body of the 3D printed object. The controller does this by controlling deposition of a conductive agent to form electrodes of the 3D printed capacitor and by controlling deposition of a dielectric agent in a dielectric region between the electrodes of the 3D printed capacitor.

Abstract: Some examples include an additive manufacturing system including a processor and a memory to store instructions. The instructions cause the processor to generate print data from received data related to a three-dimensional build object. The generated print data includes defined print data to dispensing a first agent at a build area of a build material layer, defined print data to selectively dispensing a second agent at a component receiving area within the build area of the build material layer, the second agent to locally reduce a viscosity of the build material at the component receiving area to a viscous state, and defined print data to position a component within the component receiving area at a time of the component receiving area being in a viscous state.

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.
