Chopsticks are the ultimate mature technology, unimproved for thousands of years. But now a Chinese internet company has upgraded them to tackle a very modern challenge. 筷子的发明早已经是非常成熟的技术，几千年以来就没有得到过创新。但是现在中国的一家互联网公司挑战筷子技术，将技术更新应对现代社会的挑战。 Baidu, the search engine, unveiled a prototype pair of “smart” chopsticks to form the last line of defence in Chinese diners’ battle against “gutter oil” and other food scares. 百度，一家搜索引擎公司，近期揭秘了一双“智能”筷子的原型，作为中国餐桌上抵制“地沟油“的最后一道防线。 The new chopsticks, called Kuaisou, should allow diners to take food safety into their own hands. They are fitted with electronic sensors that flash a red light when they come into contact with oil that has more than 25 per cent of total polar materials, an indicator of freshness, according to Baidu. 根据百度的说法，这种新型筷子叫”筷搜“，能够让食客们自己把握食品安全。筷搜装上了电子感应器，当筷子接触到超过25%以上的电极物质的时候，用来显示新鲜度的红灯会闪烁。 The readings picked up by the chopsticks are then relayed to the consumers’ smartphone, via a dedicated app. The chopsticks are also able to pick up a variety of other readings on food freshness, acidity and nutrients, Baidu said. However, there is no date yet for their commercial production. |
