A Feasibility Study of a Low-frequency Wearable Device for Contactless Monitoring of Blood Glucose Level

Abstract

In this paper we propose a safe, wearable and contactless device for blood glucose level monitoring based on a low frequency RF radiating system. The innovative hardware arrangement is composed by two concentric RF spiral coils, inductively coupled and able to produce a focused magnetic field distribution; hence, the monitoring sensitivity can be significantly enhanced. First, we describe the hardware system and then, we perform full-wave simulations in order to validate the feasibility of the method. The obtained results support the proposed approach and suggest the possibility to integrate the radiating system in a wearable non-invasive device for the blood glucose real-time monitoring, encouraging further analyses.
