Continuous Glucose Monitoring (CGM)

Continuous Glucose Monitoring (CGM) systems utilize ultra-low power magnetic sensing to manage power states and ensure device integrity in compact, wearable medical systems. In CGM applications, nanopower switching supports reliable shelf-life management, system wake-up, and power-gating functionality.

Overview

A CGM system typically combines an ultra-low power magnetic switch with system processing to maintain battery life during storage and enable immediate system readiness upon patient use. In battery-operated medical environments, power consumption, device size, and non-contact operation all affect system performance.

Measures magnetic field proximity to detect activation or state changes for system wake-up.

Supports CGM systems, wearable drug delivery patches, and smart medical wearables.

Requires compact sensor form factors and ultra-low nanopower standby current for long shelf-life.

Often works with MCU interrupt pins to manage system-level sleep and power-gating.
