  1. Wearable Wireless Body Area Networks (WWBAN) Presented by Jingjing He 788.11J Presentation

  2. Motivation • Statistics suggest that health care needs a major shift toward more scalable and more affordable solutions. • Wearable systems for continuous health monitoring are a key technology in helping the transition to more proactive and affordable healthcare

  3. The Main Idea • Seamlessly integrate sensor nodes into wireless personal or body networks (WPANs or WBANs) for inexpensive, non-invasive, continuous, ambulatory health monitoring with almost real-time updates of medical records via Internet.

  4. The Main Achievements • prototype sensor network for health monitoring, including system architecture, hardware and software organization • solutions for time synchronization, power management and on-chip signal processing

  5. The Challenges • synchronized time stamps for proper correlation of data coming from different sensors and for efficient sharing of communication channel • reduced total power consumption: wearable sensors means size of sensor small enough, so does the battery size

  6. WWBAN Architecture

  7. Hardware Multiple ActiS sensor nodes; Each sensor node utilizes a commercially available wireless sensor platform Telos and a custom intelligent signal processing daughter card attached to the Telos platform

  8. Innovation • The idea to use WWBAN to enable continual, unobtrusive, ambulatory heath monitoring itself is cool • In this paper, authors gave a prototype WWBAN based on off-the-shelf wireless sensor platforms and custom-designed ECG and motion sensors, which makes the idea more exciting.
