The aim of this study was implementation of a wireless patch system that can predict a patient's body temperature. The proposed patch can predict the body temperature from the skin temperature and sweat rate by using a modified Pennes bio-heat transfer equation. The proposed patch was small and lights enough to be attached to the patient's skin, and a small skin temperature transducer was built-in the patch. Further, the sweat rate was measured by using humidity sensors while the sweat was evaporating. The proposed patch was compared with commercial body temperature measuring device, and the results were found to be correlated.
