Wearable continuous body temperature (Skin Temperature) tracking algorithm: deep mathematical model calibration to exclude ambient room temperature interference

Skin temperature is the core sentinel indicator of the human immune system’s resistance to viral invasion. However, due to the huge temperature difference between indoor heating in winter and summer in Europe, pure skin electrical contacts are extremely susceptible to interference from room temperature (Ambient Temperature) and produce false alarms. The hard core of the EIP science team dismantled the high-end ring in the international market based on the heat flux (Heat Flux) calculation model. This device not only has a precision NTC thermistor, but also introduces a room temperature compensation quadratic equation algorithm. According to actual measurements, in a sudden scenario where the ambient temperature plummeted by 10 degrees, the ring’s measurement of the human body’s baseline body temperature remained robust, with an error of less than 0.08 degrees.
