Wearable Finger-Ring for Non-invasive Blood Glucose monitoring usingElectromagnetic Waves
Problem Statement

Diabetes patients face significant challenges in maintaining proper blood glucose levels due to the pancreas's inability to produce sufficient insulin or the body's ineffective use of insulin. Current monitoring methods are either invasive, causing pain and risk of infection, or non-invasive but expensive and inconvenient. As a result, many patients do not monitor their glucose levels as frequently as needed, leading to severe health complications such as heart and kidney failure, non-healing wounds, and neuropathy. There is a critical need for a more comfortable, cost-effective, and reliable method for continuous blood glucose monitoring to improve diabetes management and patient quality of life.

Abstract

Diabetes management requires frequent blood glucose monitoring, which can be painful and costly with current methods.This invention addresses this by offering a non-invasive, cost-effective solution using a simple copper ring model. This ring uses electromagnetic waves to measure blood glucose levels through the finger by detecting changes in blood properties. The design is portable, accurate, and shields against external interference, making it suitable for home and hospital use. Our approach eliminates the need for expensive test strips and invasive procedures, providing a continuous and comfortable glucose monitoring option for diabetes patients. This technology has significant potential for improving diabetes care and quality of life.

Uniqueness of the Solution
  • Non-Invasive Electromagnetic Sensing: Utilizes electromagnetic waves to measure blood glucose levels through the finger, eliminating the need for painful finger pricks and reducing the risk of infections, making it suitable for frequent, comfortable use. 
  • Simple Copper Ring Model: A single-port electromagnetic wave-based copper ring that encloses the finger, designed for robustness and ease of use, providing reliable and consistent glucose readings with minimal maintenance. 
  • Hermetically Sealed and Temperature Controlled: Enclosed in a hermetically sealed container with active temperature control, ensuring accurate glucose measurements regardless of external environmental conditions, enhancing the device’s reliability. 
  • Frequency Range Measurement (9-14 GHz): Measures the reflection coefficient (S11) at various frequencies, allowing for precise detection of blood glucose levels, thereby improving the sensitivity and accuracy of the monitoring system. 
  • Portable Design: Compact and wearable, enabling continuous and convenient blood glucose monitoring, which supports better diabetes management and user mobility. 
  • No Recurring Costs for Test Strips or Sensors: Designed without the need for expensive test strips or sensor replacements, making long-term diabetes management more economical for users. 
  • Scalable Radiator Design: Features a simple and scalable design, facilitating easy manufacturing and widespread adoption, potentially transforming diabetes care with an affordable and user-friendly monitoring device.
