AI Technical Summary
When existing wearable devices detect core body temperature, traditional methods are highly invasive and cannot achieve continuous monitoring. Furthermore, the voltage signal output by the heat flux sensor requires a high-precision ADC chip, which leads to increased device size and power consumption.
By utilizing the ECG channel of the AFE chip in ECG-DC mode to multiplex the voltage signal output by the heat flux sensor, and combining it with skin thermal resistance adaptive calibration and circadian rhythm model, accurate detection of core body temperature can be achieved.
It achieves high-precision detection of core body temperature without increasing device size and power consumption, reducing the overall power consumption of the device and improving detection accuracy.
