Sensor to control your eating & smoking habits

The sensor's got accelerometers which help it determine whether you're chewing, smoking, speaking or coughing with about 94% accuracy. It can't determine whether the food you're eating is healthy because it'll need a lot of updates. First the team will have to develop a power source so that the sensor keeps on functioning without external batteries like the prototypes. They'll then have to develop Bluetooth connectivity so that the sensor can feed all the data to your smartphone.
The team's next challenge is to shrink the sensor in size so that it can fit well within the cavities. If you're interested in knowing more about the sensor and the research project, hit the source link (PDF) that describes it.
