In Situ Copper Electroplating Turns Material Extrusion 3D Printers Into Metal–Polymer Hybrid Fabricators

open access: yesAdvanced Materials Technologies, EarlyView.
An in situ electroplating approach for MEX 3D printing is proposed, enabling copper deposition during the fabrication of conductive polymers. The method combines a printer‐integrated plating head, ML‐based g‐code control, and stop‐and‐go printing, achieving near‐bulk copper conductivity and enabling fully embedded, assembly‐free electronic components ...

Ratiometric Temperature Sensing through Alternating Current Electroluminescence

open access: yesAdvanced Optical Materials, EarlyView.
Thermoresponsive alternating current electroluminescence (ACEL) is realized in ZnS microparticles with optimized Cu, Cl, and Co tri‐doping concentrations, exhibiting a blue‐to‐green emission band shift along with increasing temperature. Based on this behavior, an ACEL‐driven temperature sensing platform is developed for quantitative temperature ...
