Description

technical field [0001] The invention relates to the field of blood sugar detection, in particular to a blood sugar detection method and device. Background technique [0002] With the development of science and technology, in the field of blood glucose detection, compared with other non-invasive blood glucose detection schemes, microwave noninvasive blood glucose detection scheme has the advantage of fast detection speed, and the basic principle of its realization of blood glucose detection is: when the microwave passes through the blood glucose solution Ions (especially sodium ions) in the blood glucose solution can affect the intended path of the microwaves. That is, the ions in the blood sugar solution present some resistance to the microwaves, reducing their amplitude and causing them to phase shift. The magnitude of this impedance is influenced by surrounding glucose molecules and varies with blood glucose concentration. [0003] Therefore, when using microwaves for no...
