The BodyBugg is a calorie counting armband that uses bio-feedback sensors to give a continuous running total of calories burned. It can store up to 12 days worth of data, before you have to use the USB port to download to a computer. Powered by a single AAA battery and offered with an optional wristwatch type display unit, this marvel of modern tech will set you back a cool $399.00 ($479.95 with display) including 2 phone sessions with a BodyBugg ‘coach’.
It utilizes a patented process for interpreting calorie burn called “sensor fusion” developed by BodyMedia, Inc. This process involves collecting a range of body-data using multiple physiological sensors instead of a single sensor, which is what other calorie estimation devices such as pedometers and heart rate monitors rely on. It’s this multi-sensor approach that enables bodybugg to “see” the wearer’s context (whether they are sitting, sleeping, jogging, walking, etc.) that makes bodybugg such a reliably accurate device for calorie expenditure estimation.
