(EN) The invention provides a method for preparing a metasurface on skin for blood glucose detection, and belongs to the field of flexible wearable electronic technology and medical health crossing technology. The blood glucose detection method comprises the steps of designing a metasurface with a resonant ring structure in advance, and establishing a model of the relation between the blood glucose concentration and the electromagnetic absorption characteristic of the metasurface through simulation; preparing a metasurface on the skin; scanning reflection spectra of the metasurface formed on the skin at different frequencies by utilizing electromagnetic waves to obtain a relation curve between the S11 parameter and the frequencies; and determining the change of the blood glucose concentration according to the model and the frequency shift of the resonance peak on the relation curve. According to the method, the electromagnetic wave metasurface which is good in skin compatibility, stable inelectromagnetic performance and high in blood glucose testing accuracy is directly constructed on the skin, the blood glucose concentration of the human body can be directly detected through the method, blood of the human body does not need to be collected, and real noninvasive detection of the blood glucose of the human body is achieved.
