Title: **Christopher Leroy Frewin: Innovator in Non-Invasive Glucose Monitoring**

Introduction

Christopher Leroy Frewin, based in Tampa, FL, is a pioneering inventor known for his groundbreaking advancements in non-invasive glucose monitoring technologies. With a remarkable portfolio consisting of six patents, Frewin's work has made significant contributions to the medical field, particularly in diabetes management.

Latest Patents

Among Frewin's latest patents is a "System and method for non-invasive blood glucose monitoring." This innovative device utilizes a non-invasive sensor, specifically a patch antenna operating in the Industrial, Scientific, and Medical Radio band (5.725 GHz-5.875 GHz). This system effectively determines blood glucose concentration by measuring the shift in the resonant frequency of the non-invasive antenna patch sensor. A radio frequency (RF) synthesizer drives the patch antenna, with output coupled to both the antenna and receiver. The device processes both transmitted and received power, converting RF signals into voltages for downstream analysis. Ultimately, this provides real-time glucose concentration readings.

Another notable patent is the "Continuous glucose monitoring based on remote sensing of variations of parameters of a SiC implanted antenna." This passive sensing system involves a biocompatible silicon carbide (SiC) antenna, permanently implanted subcutaneously. An external transmitting antenna detects changes in blood glucose levels by sending a radio signal to the implanted passive antenna. The reflections of this signal reveal modifications in glucose levels, which can then be monitored externally.
