When the chopsticks are linked to a smartphone app, they provide data about the oils detected in foods. The chopsticks can determine whether the oil is fresh or recycled--the latter of which may be toxic.
Baidu says that its chopsticks will be also be able to determine the PH levels in food and the calorie values. At a recent exhibiton at a technology conference, Baidu CEO Robin Li referred to his chopsticks as "a new way to sense the world."
