生物体信息测量电路、芯片和电子设备及测量方法
By using an excitation signal with a preset phase angle in biological measurements, the phase angle is shifted from the sensitive range to the insensitive range, and the phase shift component is eliminated after the phase shift. This solves the problem of low accuracy in biological phase angle measurements and achieves higher measurement accuracy.

AI Technical Summary
In the existing technology, the accuracy of phase angle measurement of biological organisms is low, mainly due to the insufficient accuracy of resistance and capacitive reactance measurement.
By generating an excitation signal with a preset phase angle, when the excitation signal is applied to the organism, the phase angle of the organism is shifted from a range that is sensitive to resistance or capacitive reactance to a range that is relatively insensitive to resistance or capacitive reactance. After the phase shift, the measurement is performed to eliminate the phase shift component caused by the excitation signal and obtain the true value of the organism's phase angle.
It improves the accuracy of phase angle measurement in organisms and reduces the impact of the accuracy of resistance or capacitive reactance measurement on phase angle measurement.
