How does the bodybugg measure calorie expenditure?
the bodybugg has 5 main measurement components: 1) accelerometer, 2) heat flux, 3) galvanic skin response, 4) skin temperature, 5) near body temperature. Our technology partner, BodyMedia, has spent the past 5 years optimizing all of these sensors, and fine-tuning algorithms that take the data to determine actual calorie expenditure. In studies, when comparing calorie expenditure measurements from the armband device to calorie expenditure measurements in a metabolic chamber (the gold standard of calorie expenditure measurement), the bodybugg armband achieved average accuracy rates of 92%.
