A novel approach for measuring energy expenditure in free-living humans

Annu Int Conf IEEE Eng Med Biol Soc. 2009;2009:6873-7. doi: 10.1109/IEMBS.2009.5333124.


Measuring energy expenditure (EE) in free-living humans is difficult. In this study, we validated a novel instrument that measures free-living EE from direct calorimetry, i.e. the heat produced by the body. The sensor can be worn on the upper arm and measures all four forms of heat flux--conduction, convection, radiation and evaporation. The accuracy of this device was compared to a whole-room indirect calorimeter.
