Title
(EN) Method for preparing metasurface on skin for blood glucose detection
(ZH) 一种在皮肤上制备超表面用于血糖检测的方法
Abstract
(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.
(ZH) 本发明提供一种在皮肤上制备超表面用于血糖检测的方法,属于柔性可穿戴电子技术和医疗健康交叉技术领域。其中,血糖检测方法包括:预先设计具有谐振环结构的超表面,通过模拟建立血糖浓度与所述超表面的电磁吸收特性之间关系的模型;在皮肤上制备超表面;利用电磁波扫描所述皮肤上形成的超表面在不同频率下的反射光谱,得到S11参数与所述频率之间的关系曲线;根据所述模型以及所述关系曲线上谐振峰的频移,以确定血糖浓度的变化。本发明实现了在皮肤上直接构筑形成与皮肤相容性好的、电磁性能稳定、血糖测试准确性高的电磁波超表面,并且,该方法可直接检测人体的血糖浓度,无须采集人体血液,实现了真正无创地检测人体血糖。
