Patch type sensor module for estimating the energy expenditure

The patched type sensor module for estimating the energy expenditure was developed and evaluated. The Airbeat3 systems can real-time monitor heart rate and movement index. The relation test on the heart rate for the motion artifact shows the error rate within 5%. The purpose of this study was to use the combined heart rate and movement sensors method for measuring energy expenditure against indirect calorimetry. The subjects were participated in gradual exercise test on treadmill. The energy expenditure was considered as 5kcal per liter of O₂ consumed. The preliminary results of correlation equations for the Airbeat3 systems provided similar estimates of activity and energy compares with the indirect calorimetry system. But deduced algorithms show poor accuracy repeatability than the calorimetry system and more experiments should examine to enhance the precise estimates of energy expenditure.
