Tired of having to catalog every meal in your favorite fitness app just to get a sense of whether or not you're burning enough energy? You might get some relief in the near future. The University of Alabama has built an ear-worn sensor that estimates your food intake by tracking your chewing. The Automatic Ingestion Monitor (AIM) combines imagery of your meals with jaw vibrations to determine both the volume and energy levels of whatever you're eating. It's smart enough to filter out talking, so you won't throw it off by holding conversations in between bites.
