RF Biosensor having RF bandpass structure method for sensing physiological data using a biosensor and method for manufacturing a biosensor having a RF bandpass structure

摘要

A biosensor having an RF bandpass structure, a biosensor data sensing method using the same, and a method of manufacturing an RF biosensor having a metal line and an air-bridged structure are disclosed. The RF biosensor, which consists of a corrugated metal line including an air-bridge structure, detects the change in resonant frequency depending on the permittivity of a substance to be measured such as serum and D-glucose, and determines the concentration of the substance to be measured such as glucose concentration I understand. The surface of the corrugated metal line constituting the RF biosensor is coated with gold (Au), the surface roughness of a predetermined size is realized by using the etching, and the dielectric constant of the material to be measured located in the air- The change of the resonance frequency due to the capacitance of the biosensor is detected and the concentration of the substance to be measured is measured based on the change of the resonance frequency.;
