Health Monitoring Medical Patch

Overview

Description

In healthcare facilities, especially those caring for vulnerable populations such as memory care (or patients with Alzheimer's), continuous health monitoring and patient tracking are crucial.

This health monitoring patch provides real-time vitals monitoring (e.g., heart rate, body temperature) to alert caregivers to potential health issues and anomalies, ensuring timely care and logging health metrics for smarter healthcare insights. Additionally, the integration of locationing technology—leveraging Renesas' Asset Tracking and Locationing at Scale (ATLAS) and Crowdsourced Locationing (CSL)—enables caregivers to respond swiftly to wandering incidents, ensuring timely assistance and improved facility management.

System Benefits:

  • Availability of both NFC and pogo pin charging variants offers flexibility in form factor and charging preferences, accommodating diverse healthcare facility needs.
  • Energy-efficient design extends uptime between charges while ensuring continuous health monitoring and patient tracking—delivering peace of mind for both caregivers and patients.
  • Multi-core Bluetooth® SoC supports advanced data processing and logging, extended range, and reliable connectivity while maintaining low power consumption for long-lasting operation.
  • Single-component AnalogPAK IC seamlessly connects to health sensors (e.g., ECG electrodes) and integrates advanced analog features like op amps and comparators in a compact package, reducing BOM costs and enhancing patient comfort.
  • Flexibility in locationing technology from ATLAS to CSL enables flexible tracking deployments across independent living, home care, or professional healthcare facilities like hospitals and nursing homes.
