This technology develop a “Thermoelectric Ever-Charge Portable Charger” for the applications in auxiliary charging of consumer electronicsfast self-charging for outdoor sensors. Technically, a sputtering depositiona semiconductor photolithography technique are combined to fabricate p-n materialsconnection procedures. The thermoelectric performance of the device is further optimized through a low-temperature heat treatment.

Current 5G communication devices have a huge demand in high resolutiondensity of metal conducting wires in electronics ( 40 μm line width/line spacing), which cannot be achieved by conventional screen printing (100 μm). Our group cooperated with Ample Technology to develop a new-generation silver conductive paste which enables photolithographyachieves outstanding line resolution (5 μm width/13 μm spacing). The paste is simple to useperforms comparable of those of major European, AmericanJapanese manufacturers.

This technology proposes the preparation of Anodic Aluminum Oxide (AAO) templates on the surface of aluminum. The structural color of AAO is combined with lithography process to form patterns on the substrate, which can achieve high resolution on various aluminum substrate for decoration. Also, rewritable boardinvisible anti-counterfeiting technology are proposed for innovative applications by the low-cost, high-efficiency,high-saturation AAO structural colorpatterning.
