Episode 25 – Munch-o-matic: Scientists develop the artificial mouth
For years, scientists have tried to build an electronic tongue, a robot that could taste and smell food like we do. But before machines learn to taste their food, they first need to learn how to chew it. Scientists recently designed an artificial mouth that mimics the first vital steps of human digestion -- chewing, saliva release and the initial breakdown of food.
