Blood Glucose Monitor (BGM)

Overview

Description

Diabetes management is a critical aspect of global healthcare, with millions of individuals relying on accurate glucose monitoring to maintain their health. Blood glucose monitors (BGMs) are widely used for glucose monitoring due to their affordability, accessibility, and suitability for intermittent readings. They are especially preferred by individuals with Type 2 diabetes who manage their condition through lifestyle changes or oral medications rather than insulin therapy.

Renesas provides two BGM systems featuring multifunctional MCUs or SoCs with integrated analog front-end (AFE) or power management. These designs enable compact, cost-effective glucose monitoring with scalable features to address diverse application needs.

System Benefits:

  • Optional Bluetooth® Low Energy (LE) and/or NFC for seamless data transmission to mobile devices and healthcare systems, enhancing long-term tracking and health data logging.
  • Multifunctional MCUs and SoCs reduce the bill of materials (BOM), enabling smaller form factors and cost-effective solutions without compromising functionality.
  • Low-power system design extends operational time, minimizing battery replacements for improved user convenience.
  • Ultra-low power MCU with integrated AFE and drivers, optimized for glucose level readings in a single-chip solution.
