Wearable Approach for Contactless Blood-Glucose Monitoring by Textile Antenna Sensor
In this work, a new approach for non-invasive monitoring of blood glucose concentration is presented. This approach is based on the adoption of an anten-na sensor designed on a textile substrate, thus realizing a wearable sensing de-vice able to assure greater discretion and less discomfort to diabetes patients. The antenna is numerically validated by assuming a stratified medium under test well simulating the human finger. As a further enhancement, an accurate dielec-tric model is adopted for blood, which specifically considers its dispersive be-havior in terms of dielectric constant and tangent loss factor when changing the glucose concentration. Some preliminary numerical results are discussed to prove the effectiveness of the proposed wearable antenna sensor.
