Body temperature measuring device, body temperature measuring system, body temperature measuring method

摘要

A body temperature measuring device (1) that is non-electric and non-contact, capable of measuring body temperature with high accuracy, and capable of easily increasing the accuracy of body temperature measurement by upgrading the software is provided. A body temperature measuring device (1) includes a body temperature detecting unit (11) and a terminal device (10). The body temperature detection unit 11 includes a power supply unit 11b that converts an audio output signal from the terminal device 10 into electric power, a detection unit 11c that detects infrared energy from the user's skin surface as a temperature detection signal, and the temperature detection signal. Is converted to an audio input signal. The terminal device 10 calculates oscillation means for oscillating an audio output signal to the body temperature detection unit 11, an audio input signal received from the body temperature detection unit 11, the emissivity of the skin surface of the user, and calculation within a predetermined measurement time. Measuring means for estimating the surface temperature of the small change amount as the body temperature of the user based on the change amount of the surface temperature with time.
