Statistical Estimation of Body Temperature from Skin Temperature for Smart Band

As wearable devices have been activated, smart band functions are becoming more diverse. They have many functions that measure a person's physical activity, and body temperature is one of them among these functions. Therefore, this paper proposes a statistical evaluation method based on actual body temperature measurement values for smart band's body temperature measurement. The proposed method estimate skin temperature to body temperature by obtaining two approximate Gaussian functions and mapping these Gaussian functions to each other. This is the application of the central limit theorem of statistics. The proposed method will verifies the accuracy and validity of the body temperature assessment through our experiments.
