A cell phone based health monitoring system with self analysis processor using wireless sensor network technology

Area of Science:

• Biomedical Engineering
• Telemedicine
• Wireless Health

Background:

• Chronic disease management requires continuous patient monitoring.
• Existing remote monitoring systems face limitations in connectivity and local analysis.

Purpose of the Study:

• To develop an integrated wireless healthcare monitoring system for ubiquitous disease and chronic management.
• To incorporate a standalone electrocardiogram (ECG) diagnosis algorithm for cell phone-based local analysis.

Main Methods:

• Utilized a CDMA-based wireless system with dongle prototypes and tiny wireless sensors.
• Implemented an 802.15.4 wireless local area network (WLAN) for in-hospital monitoring.
• Enabled remote data transmission via cell phone using the CDMA network for out-of-LAN coverage.

Main Results:

• Demonstrated a functional prototype for remote physiological sign monitoring.
• Integrated a standalone ECG diagnosis algorithm for local, real-time signal evaluation.
• Facilitated wireless data transmission to medical centers or PDAs.

Conclusions:

• The developed system offers a flexible and integrated solution for ubiquitous healthcare monitoring.
• The standalone ECG diagnosis enhances local patient evaluation before data transmission.
• The system supports continuous monitoring across hospital, home, and travel settings.
