Project Overview

• Demonstrate the feasibility of wireless power
  transmission through the example of wireless
  bridge monitoring sensors.

3
Goals

• Wireless power collection
• Characterization of low power transceivers
  (TNCs)
• Develop at least one sensor type
• Separate antennas for power and communication
• Bi-directional serial communication between
  sensor and base station
• Communication through 1 of concrete
