Title:
TEST SUBSTANCE CONCENTRATION MONITORING CIRCUIT AND SYSTEM, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/238808
Kind Code:
A1
Abstract:
An electric-current test substance concentration monitoring circuit and system, and a terminal device. In the monitoring circuit, a biosensor signal pre-processing module is added. The module has two output ends such that the flow of a current signal can be controlled. When the current signal flows to an alternating-current impedance measurement module, the alternating-current impedance measurement model can be used to adjust the test substance concentration calculation method, thereby ensuring the accuracy of calculation of test substance concentration.
