Introduction
Diabetes management is a critical aspect of health for millions of individuals worldwide, particularly for those with insulin-dependent diabetes. Continuous glucose monitoring (CGM) has emerged as a revolutionary tool in this domain, providing real-time glucose levels to help patients maintain optimal blood sugar levels. The development of a low-power, wireless biosensor for CGM represents a significant advancement in diabetes care, enhancing the quality of life for patients and improving health outcomes. This blog will delve into the technological advancements and implications of these biosensors.
What is Continuous Glucose Monitoring?
Continuous glucose monitoring involves the use of a small device that tracks glucose levels in the interstitial fluid just beneath the skin. This technology allows patients to receive real-time data about their glucose levels, which is crucial for effective diabetes management. The key components of a CGM system include:
- Sensor: Measures glucose levels continuously.
- Transmitter: Sends data wirelessly to a receiver.
- Receiver: Displays glucose readings and trends.
