- Abstract: I performed this study under the supervision of Assistant Professor Babak Moaveni in order to complete the requirements for an undergraduate Senior Thesis at Tufts University. Vibration-based structural health monitoring can detect damage on a structure with the use of sensors and data acquisition systems. Previously at Tufts University, a research group implemented a wired sensing system ... read moreon the Dowling Hall Footbridge to determine the dynamic parameters of the bridge. If the bridge’s dynamic parameters change, it indicates a change in the bridge’s structural properties, and therefore damage is detected. This research project focuses on the investigation of possible wireless sensing options for the same bridge. Sensors were compared based on specifications such as their sensitivities and noise floors. Once a sensor was chosen, it was evaluated on a shaker alongside different types of wired accelerometers. An error analysis was performed to quantify the variability of the measurements. Finally, the new wireless sensor was implemented on the Dowling Hall Footbridge to further evaluate the feasibility of an entire wireless array with it.read less
