Wearable Respiratory Monitoring System

01

Overview

CoBuild Labs developed a compact, wearable respiratory monitoring system designed for continuous and accurate respiration rate measurement in both clinical and remote healthcare environments. The lightweight chest strap enables comfortable long-term monitoring while wirelessly transmitting real-time respiratory data to healthcare providers and connected applications.

The Challenge

Developing a reliable wearable respiratory monitoring device requires balancing measurement accuracy, user comfort, and continuous connectivity. The client required a solution that could provide dependable respiratory monitoring for extended periods without compromising wearability. The key engineering challenges included:

• Designing an ergonomic chest strap that remains comfortable during prolonged wear.
• Positioning the sensor below the chest and above the diaphragm to maximize respiration signal quality.
• Ensuring stable sensor contact despite body movement.
• Achieving continuous, low-latency Bluetooth Low Energy (BLE) data streaming.
• Providing accurate real-time respiration rate estimation.
• Generating configurable alarms when the respiration rate falls below or rises above critical thresholds.
• Developing a compact and lightweight wearable suitable for hospital and home-care environments.

Our Engineering Solution

CoBuild Labs designed and developed the complete wearable respiratory monitoring solution, including custom electronics, embedded firmware, wearable mechanical design, and wireless communication architecture. The system continuously captures respiratory activity, calculates respiration rate in real time, and securely streams data via Bluetooth Low Energy to a connected host device. Integrated alarm functionality immediately notifies caregivers or monitoring systems when respiration rates exceed predefined safety thresholds, making the platform suitable for bedside monitoring, telemedicine, and remote patient monitoring applications.

• End-to-end wearable architecture spanning electronics, firmware, soft-goods, and BLE telemetry.
• Optimized sensor placement for accurate respiration signal acquisition during movement.
• Real-time respiration rate estimation with configurable high/low threshold alarms.
