Portable VO₂ and VCO₂ Metabolic Monitor

Project period: Jan 2024 – Apr 2024

Role: CAD, embedded programming, BLE integration, and MATLAB interface development

  • MATLAB
  • Bluetooth Low Energy
  • Embedded systems
  • CAD
  • Sensor acquisition

Project Overview

This project developed a portable prototype for monitoring oxygen-consumption and carbon-dioxide-production signals used in metabolic assessment. The work connected the physical enclosure, embedded acquisition code, Bluetooth Low Energy communication, and a MATLAB interface into one data-collection workflow.

My Contributions

  • Designed the prototype packaging and component layout in CAD.
  • Implemented embedded code for sensor acquisition and communication.
  • Integrated BLE for wireless transfer of live measurements.
  • Developed the MATLAB-side interface for receiving and displaying the data.

System Workflow

The embedded device acquires the gas-related sensor channels, packages the measurements, and transmits them over BLE. MATLAB receives the stream and provides the host-side interface for real-time observation and subsequent analysis.

Outcome

The project established an end-to-end prototype from sensing hardware to wireless visualization. Additional public design files and quantified validation results are not currently included with this portfolio entry, so the page intentionally limits its claims to the implemented architecture and demonstrated data path.
