Wearable electronics are often used for estimating the energy
expenditure of the user based on heart rate measurement. While heart
rate is a good predictor of calorie consumption at high intensities, it
is less precise at low intensity levels, which translates into
inaccurate results when estimating daily net energy expenditure. In this
study, heart rate measurement was augmented with heat flux measurement,
a form of direct calorimetry. A physical exercise test on a group of 15
people showed that heat flux measurement can improve the accuracy of
calorie consumption estimates especially during rest and low-intensity
activity when used in conjunction with heart rate information and vital
background parameters of the user.
