The project Glucolate aims to use state-of-the-art microwave technology to develop sensors able to track the variations in the blood glucose level. This is an ambitious approach that relies on the changes in the dielectric permittivity of the biological tissues induced by the different blood glucose level. In this sense, accurate microwave circuits sensitive to the effective relative permittivity of the environment are proposed. In this site, updated information and additional material for this research will be periodically posted.
