At first sight, it may look strange but Tokyo-based Nitto Kagaku’s Kami Kami sensor [JP], a device tailor-made for children counting the number of bites they make while eating food, actually seems to have a right to exist.

Parents can control whether their kids chew their food properly through the sensor, which tries to motivate the little ones by making sounds after every 30 and 1,000 bites. The sensor itself weighs 40 grams while the fish-shaped counter weighs 148 grams. Three AAA size batteries are enough for 30 hours of operation.

Nitto Kagaku sells two versions of the Kami Kami, one for elementary school kids and one for middle-school children. Both versions cost $110 each. Nitto Kagaku seems to be a Japan-oriented company so that you can’t expect to see the sensor outside Nippon soon.
