Last years CES brought us the Hapifork, one of the more unusual entries in the rapidly growing category of sensor-equipped devices designed to track the quantified self. At CES 2014, another French startup is taking that idea and running with it to produce something even more outlandish — meet the Kolibree smart toothbrush. Kolibrees product is designed to outsmart your dentist, in the companys words, by analyzing your brushing and letting you track your habits over time through an app for Android and iOS devices.
