Traditional blood glucose monitoring often requires painful finger pricks or invasive sensors, leading to discomfort, risk of infection, and user dissatisfaction. Even non-invasive devices, like GlucoWatch®, faced issues such as skin irritation, calibration delays, and inaccuracies, especially during physical exertion.
Core Features
This invention introduces a painless, non-invasive blood glucose meter that continuously monitors glucose levels using reverse iontophoresis. A self-adhesive sensor, worn on the skin, uses a gentle electric current to extract glucose molecules from interstitial fluid for measurement. The sensor integrates advanced materials, such as Prussian blue and catalytic enzymes, and transmits real-time data wirelessly to devices like smartphones.
Inventive Step
Unlike prior devices, this meter avoids needles, skin irritation, and interference from sweat or other fluids. Its reverse iontophoresis process ensures high accuracy by directly capturing glucose molecules. The innovative use of specialized electrochemical materials enables precise glucose detection, setting it apart from existing solutions.
Benefits
- Painless and convenient: Eliminates finger pricks and discomfort.
- Continuous monitoring: Tracks glucose levels in real-time, offering alerts for abnormal ranges.
- Cost-effective: Durable, reusable components minimize expenses.
- Improved accuracy: Delivers results comparable to laboratory tests without interference from other fluids.
Broader Impact
This technology revolutionizes diabetes care, enhancing patient compliance and quality of life. It reduces the risk of infection, promotes better disease management, and contributes to healthcare sustainability by minimizing disposable components. By improving glucose monitoring, it supports broader efforts to combat the global diabetes epidemic, ultimately improving public health outcomes.
