METERING DEVICE FOR BLOOD GLUCOSE CONCENTRATION BASED ON MICROWAVE SIGNALS

Non-invasive measuring device for measuring blood glucose concentrations on a user's finger, based on microwave signals sensitive to differences in electrical permittivity caused by changes in blood glucose concentration, comprising a rectangular cross-sectional hollow prismatic resonant cavity, which is filled with a dielectric material, an antenna and a mold; a signal-generating means capable of generating microwave signals connected to the antenna through a signal-differentiating means; a signal-detecting means connected to the antenna through the signal-differentiating means; at least one means of control, connected to the signal-detecting means and to the signal-generating means, which controls signal generation and signal reception from the signal-detecting means.
