Overview

  • WiFi CSI-based patient monitoring MVP for bed-state classification, fall-risk event detection, and respiration monitoring.
  • Designed a camera-free monitoring system that uses wireless channel changes around a hospital bed to detect patient state and risk events.

My Contribution

  • Built the MVP pipeline for CSI window features, model comparison, and monitoring-oriented classification.
  • Organized the system around practical privacy-preserving patient monitoring scenarios.

Highlights

  • Classified bed-related states such as lying, standing, moving, leaving bed, and fall-like risk events.
  • Used WiFi CSI signals as a privacy-preserving alternative to camera-based monitoring.
  • Explored lightweight deep learning models for practical monitoring scenarios.

  • WiFi CSI-based patient monitoring MVP for bed-state classification, fall-risk event detection, and respiration monitoring.
  • Designed a camera-free monitoring system that uses wireless channel changes around a hospital bed to detect patient state and risk events.

My Contribution

  • Built the MVP pipeline for CSI window features, model comparison, and monitoring-oriented classification.
  • Organized the system around practical privacy-preserving patient monitoring scenarios.

Highlights

  • Classified bed-related states such as lying, standing, moving, leaving bed, and fall-like risk events.
  • Used WiFi CSI signals as a privacy-preserving alternative to camera-based monitoring.
  • Explored lightweight deep learning models for practical monitoring scenarios.
