【Application Solution】 Low Power Consumption Enables Long Endurance, AWINIC Chips Empower Continuous Glucose Monitoring

2026-06-17

In the field of health management, Continuous Glucose Monitoring (CGM) has become an indispensable necessity for diabetic patients. China has a vast diabetic population, and patients with type 1 diabetes, type 2 diabetes requiring intensive insulin therapy, and gestational diabetes, in particular, urgently need accurate and continuous glucose data to scientifically guide treatment plans.

Traditional fingertip blood sampling is not only inconvenient to operate but also fails to capture blood glucose fluctuations during critical periods such as at night or after meals, making it easy to miss risk warning signals. In contrast, Continuous Glucose Monitors (hereinafter referred to as CGM) can display real-time dynamic blood glucose trend curves, provide early warnings of high and low blood glucose risks, and help patients adjust their diet, exercise, and medication regimens in a timely manner, truly shifting blood glucose management from passive response to active protection.

In response to the stringent demands of Continuous Glucose Monitors (CGM) for miniaturization and long endurance, AWINIC Technology has launched a series of small-package, low-power complete solutions, covering key components such as Hall switches, load switches, boost DC-DC converters, and operational amplifiers. The specific application architecture is as follows:
