摘要: Direct writing technique to build micro/nano structures for flexible electronics and bioengineerings shows unique advantages of simplicity, fast low cost et al. In order address its problems high fluid transport resistance in the pipeline, blockage nozzle slow responses speed, rod-climbing effect is introduced direct using a micro-channel rotation shaft within channel as pump fluid. The solution flow rate this was studied without applied voltage line width could be controlled by changing speed. response time liquid supply can reach 0.3 s with speed changed from 500 r/min 9000 r/min, which much smaller than that traditional syringe pump. Furthermore, when voltage, nanoscale wires were obtained. Thus, such Weissenberg might great potential rapid manufacturing electronic future.
