  1. NASA SpaceCommunications Symposium Biosensor Networks Principal Investigators: Frank Merat, Wen H. Ko Task Number: NAG3-2578 Case Western Reserve University September 18, 2002

  2. The goal of this project is to develop a test platform for biomedical monitoring using COTS components and state-of-the-art communications concepts. Start date March 2001. Biosensor Networks • Project Overview Biomonitoring Network Body drawing from Fundamentals of Bioelectrical Impedance Analysis, Rudolph J. Liedtke, RJL Systems, February 1998.

  3. This technology has applications for continuous health monitoring of humans in space and for long duration space experiments involving humans and/or animals. Any wireless solution should interface with existing and future proximity networks. Biosensor Networks • Enterprise Relevance “A Lightweight Ambulatory Physiological Monitoring System,” NASA Tech Briefs, January 2001.

  4. The major impact of this technology is upon manned missions, e.g., space station and shuttle missions . Removal of wires and other encumbrances would improve astronaut freedom of movement and increase the system reliability. Biosensor Networks • Enterprise Impact Wireless Biosensor Network

  5. Biosensor Networks • Milestones - Technical Accomplishments and Schedules Feasibility Experiment Body drawing from Fundamentals of Bioelectrical Impedance Analysis, Rudolph J. Liedtke, RJL Systems, February 1998.

  6. Biosensor Networks • Milestones - Technical Accomplishments and Schedules

  7. Biosensor Networks • Milestones - Characterize human body as rf communications channel Received Power Through the Body (underside of forearm with 30 cm separation). Antenna dimensions: L =39 mm, W = 42 mm, and h = 0.062” on FR-4 substrate. Geometry of Basic Rectangular Patch Antenna Received Power at 1 m separation. Antenna dimensions are L = 41 mm, W = 38 mm, and h = 0.062” on FR-4 substrate. Received Power at 50 cm separation. Transmitter antenna: L = 54 mm, W = 48 mm, h = 0.062”; receiver antenna L = 26 mm, W = 38 mm, h = 0.062”, both on FR-4 substrate.
