  • Abstract:
    In this work, a previously developed structural health monitoring (SHM) system was advanced toward a ready-for-implementation

    system. Improvements were made with respect to automated data reduction/analysis, data acquisition hardware, sensor types, and

    communication network architecture.

    This report volume (Volume III) summarizes the energy harvesting techniques and prototype development for a bridge monitoring

    system that uses wireless sensors. The wireless sensor nodes are used to collect strain measurements at critical locations on a

    bridge. The bridge monitoring hardware system consists of a base station and multiple self-powered wireless sensor nodes. The

    base station is responsible for the synchronization of data sampling on all nodes and data aggregation. Each wireless sensor node

    include a sensing element, a processing and wireless communication module, and an energy harvesting module.

    The hardware prototype for a wireless bridge monitoring system was developed and tested on the US 30 Bridge over the South

    Skunk River in Ames, Iowa. The functions and performance of the developed system, including strain data, energy harvesting

    capacity, and wireless transmission quality, were studied and are covered in this volume.
