Description

technical field [0001] The application belongs to the technical field of electrochemical test paper, in particular to an electrochemical test paper capable of continuously detecting substrates. Background technique [0002] In the detection of medicine or biochemistry, the use of electrochemical test paper has been a common technology. The traditional electrochemical test paper has two electrodes, after the sample is injected into the reaction area of ​​the test paper, the electrical properties of the sample are measured by these two electrodes. [0003] At present, some indicators require patients to monitor and measure indicators every day. For example, patients with hypertension need to measure their blood pressure every day, patients with hyperglycemia need to measure their blood sugar every day, patients with hyperlipidemia need to measure their blood lipids every day, and patients with heart disease need to measure their blood lipids every day. Measure heart rate, etc...
