Description

technical field [0001] The invention relates to a mobile glucose detection device with low power consumption, in particular to a mobile glucose detection device capable of wireless communication with a mobile phone, which has the advantages of fast detection, low power consumption, high integration, small size, and less demand for sample liquid. Advantages such as large-scale production. Background technique [0002] With the rapid development of society and the continuous improvement of living standards, people are paying more and more attention to their own health issues. Diabetes mellitus is a metabolic disease characterized by hyperglycemia, and it is also a relatively common chronic disease with a wide age distribution of the affected population. By detecting the overall level of glucose in human blood, it is the best way to diagnose and treat diabetes in time. Therefore, many diabetic patients need to carry a glucose detection instrument with them to detect the gluco...

AI Technical Summary

Problems solved by technology

[0018] From the perspective of integration with mobile phones, electrochemical sensing and detection methods have the following disadvantages: 1) Compared with mobile devices such as mobile phones, their energy consumption is relatively high

2) Its detection circuit is not compatible with existing integrated circuit technology and is not suitable for mass production

3) Since the measurement is completed through the oxidation-reduction reaction of electron exchange, the sample liquid is directly damaged, and repeated measurements cannot be performed

This connection method is a wired connection, which has a lot of inconvenience compared with a wireless connection.
