Abstract
An electronic device may include: a first temperature sensor configured to measure a first temperature of a skin surface when a user comes into contact with a main body of the electronic device; a first heating element spaced apart from the first temperature sensor by a first predetermined distance; a second temperature sensor spaced apart from the first heating element by a second predetermined distance and configured to measure a second temperature inside the main body; and a processor configured to: estimate heat flux based on the first temperature and the second temperature; estimate a blood perfusion rate of the user based on a temperature of the first heating element and the first temperature, and estimate a core body temperature of a user based on the first temperature, the estimated heat flux, and the estimated blood perfusion rate.
