Abstract
A method of fabricating metasurface on skin for blood glucose detection, which relates to a flexible wearable electronic technology in healthcare. The blood glucose detection comprises: designing metasurface with a resonant ring structure cell, and building a model by simulating a relationship between blood glucose concentration and electromagnetic absorption property of the metasurface; preparing the metasurface on the skin; scanning the metasurface on the skin under different frequencies electromagnetic wave and acquiring a relationship curve between S-11 parameter and frequency; the change of blood glucose concentration is determined according to the resonant peak frequency shift in the relationship curve based on the model. It realizes the electromagnetic wave metasurface with a good skin biocompatibility, a stable electromagnetic property and a high glucose detection accuracy is directly structured on the skin, moreover, it can directly measure human blood glucose concentration without sampling human blood, realizing real non-invasive human blood glucose detection.
