Baidu smart chopsticks
It all started as a April fools’ prank last spring: chopsticks that are able to analyze the quality of food. This summer Chinese web giant Baidu launched a prototype of smart chopsticks that focuses on health and hygiene. The smart chopsticks will tell you whether the oil that has been used is fresh: sensors of the chopsticks discover the oil’s temperature and judges its fitness for consumption. Poor food safety is a big problem in China, one of the concerns is ‘gutter oil’. ‘Gutter oil’ is illegal cooking oil what is made by reprocessing waste oil or by dredging up leftovers from restaurants.
