技术如何印制出无法伪造的纸币一直是各国印钞厂所面临的一大难题。德国和日本研究人员日前试验了一种更简单有效的防伪技术:直接在纸币上印刷微型有机电路。研究人员以美元、瑞士法郎、日元及欧元作为试验对象,直接在这些钱币上印上氧化铝、金及有机分子,形成薄膜晶体管层。该组研究人员成功地在每张纸币上印上100层有机超薄型薄膜晶体管,这些薄膜晶体管阵列仅需3伏的电压即
How printing technology can not be counterfeit banknotes has always been a major problem faced by printing money in various countries. Researchers in Germany and Japan have tested a simpler and more effective anti-counterfeiting technology: Printing micro-organic circuits directly on banknotes. Researchers in the dollar, the Swiss franc, the Japanese yen and the euro as the test object, directly on these coins printed on alumina, gold and organic molecules to form a thin-film transistor layer. The researchers successfully printed 100 sheets of organic thin film transistors on each banknote. These thin film transistor arrays only need a voltage of 3 volts
