Diabetes is the third most serious disease that endangers human health in the world. At present, the diagnosis method of diabetes is to collect venous blood, which is an invasive method, which can easily cause patients to resist and affect treatment. Breath detection technology has the characteristics of non-invasive, convenient and fast, and the study found that breath acetone can be used as a breath marker for diabetic patients. Compared with large-scale breath detection equipment such as chromatography and mass spectrometer, gas sensor has the characteristics of small size, easy operation and low cost, so the method of using gas sensor for breath detection has become a research hotspot.

According to the International Diabetes Federation(IDF)In2019The ninth edition of the Global Overview of Diabetes released in:2019About a year globally.4.63Hundreds of millions of people suffer from diabetes, while the number of people with diabetes in China is1.164billion, ranking first in the world. and is expected2045The world will have up7Hundreds of millions of people suffer from diabetes, and the number of people with diabetes in China will be as high1.472Billion. The above data show that the number of diabetes patients in China and the world has not been effectively controlled but is becoming more and more serious.

In the human body, acetone is formed by metabolism or lipolysis leading to ketonization, so changes in acetone concentration can provide information on important metabolic changes occurring in the body. Acetone is the hallmark gas exhaled by diabetics. It is about 0.3-0.9 ppm for healthy people and more than 1.8ppm for diabetics. The analysis of the concentration of acetone gas exhaled by human body is a screening method for rapid diagnosis of diabetes.

Compared with healthy people, diabetic patients show higher acetone concentrations due to lower insulin levels, and fasting and caloric restriction also cause higher acetone concentrations.

Acetone analysis is a non-invasive analysis method that represents the level of blood ketone bodies. It can not only diagnose diabetes, but also is an important detection index of liver fat metabolism. For example, the ketone-raising diet used for diabetes treatment and weight control will obviously increase this index. Aerobic exercise will also increase the liver fat metabolism rate, and the blood and respiratory acetone levels will also increase.

Therefore, an efficient and reliable acetone gas sensor can measure the change of acetone content in human respiratory gas, which is very necessary for the early warning of human health status and non-invasive diagnosis of diseases.
