This Innovations Deserving Exploratory Analysis (IDEA) project developed a prototype system that uses bridge vibration created by passing traffic to power a monitoring device. This monitoring device has no need for an external power source and can be completely embedded into the structure. The designed system has been tested and validated in field conditions, remaining on the RT11 bridge in Potsdam, New York for as long as a week. The results of experiments show that while energy availability varies by the hours and day of the week, on average the sensor was capable of performing 24-hour monitoring of the bridge. The results validate the proposed approach to energy harvesting and suggest that continuous monitoring of bridge infrastructure can be performed by self-powered sensors.
