The bodybuggâ¢ (note the aggressively lowercased trademark) monitors your motion, heat flux, galvanic skin response, skin temperature and near body temperature (not sure how heat flux is different from what could be calculated from the two temperatures) and determines your daily energy expenditure.
It isn’t clear exactly how this data is all put together. You need to go on line and you can also enter what you have eaten, and the result is something like a daily net Calorie deficit or surplus.
What do all these devices have in common? The Sleeptracker, the bodybugg, and the Polar 625X all contain accelerometers, the last two both have 2-axis accelerometers, I don’t know if this is true of the Sleeptracker also. The bodybugg can apparently also be used for sleep monitoring and can receive signals from a Polar heart rate transmitter.
How long until we have a consumer level device that you can wear 24×7 that will monitor your speed, position, exertion, heart rate and energy inputs and can be dumped to your computer, or sent to your doctor?
