Book Description
Energy harvesting is a promising and evolving field of research capable of supplying power to systems in a broad range of applications. In particular, the ability to gather energy directly from the environment without human intervention makes energy harvesting an excellent option for powering autonomous sensors in remote or hazardous locations. This dissertation examines the possibility of using energy harvesting in new and innovative ways to power wireless sensor nodes placed in the substructures of highway bridges for structural health monitoring. Estimates for power requirements are established, using a wireless sensor node from National Instruments as an example system. Available power in a bridge environment is calculated for different energy sources, including solar radiation, wind, and vibration from traffic. Feasibility of using energy harvesting in such an application is addressed for both power availability and cost as compared with grid power or primary batteries. An in-depth functional analysis of existing energy-harvesting systems is also presented, with insights into where innovation would be most beneficial in future systems. Finally, the development of a suite of complementary energy-harvesting devices is described. Because conditions on bridges may vary, multiple solutions involving different energy domains are desired, with the end user able to select the harvester most appropriate for the specific installation. Concept generation techniques such as mind-mapping and 6-3-5 (C-Sketch) are used to produce a wide variety of concepts, from which several promising concept variants are selected. The continued development for one concept, which harvests vibration using piezoelectric materials, is described. Analytical modeling is presented for static and dynamic loading, as well as predicted power generation. Two proof-of-concept prototypes are built and tested in laboratory conditions. Through the development of this prototype, it is shown that the example wireless sensor node can successfully be powered through energy harvesting, and insights are shared concerning the situations where this and other energy harvesters would be most appropriate.

Book Description
The work described in this thesis discusses the design of a solar energy harvesting system to support a structural health monitoring system. The objective was to design a photovoltaic system capable of powering a wireless gateway and cellular modem, a static DC 14W load, while meeting certain functional and energy requirements for deployment on a bridge. A literature review of the application, technologies, components, and latest innovations in solar energy technology was completed. A methodology for designing a system for attaching energy harvesting systems onto bridges while meeting design requirements is presented as a tool for engineers and students. The use of the tool was demonstrated through a study which revealed that the methodology aided in producing concepts that were higher in quality, quantity, and better met design requirements. A PV array performance model was used to determine the proper PV module size, battery bank size, panel orientation, the usefulness of a solar tracker and MPPT charge controller, and whether the use of two separate PV modules with independent geometric orientations provide better performance as compared to a single larger panel. It was found from the study that the optimal PV system design specifications were a 120W Polycrystalline PV panel, a 120 A-hr LiFePO4 battery bank, a 45 degree tilt and 0 degrees solar azimuth angle (south), and an MPPT controller. The results from the analytical model also showed that the maximum energy produced with two independent panels would be at a solar azimuth angle of 0 degrees (south) and tilt angles of 45 and 50 degrees respectively. However, these energy gains were insignificant compared to simply increasing the size of the PV module. This result was verified by physical experiments. The physical embodiment of the solar energy harvester with these characteristics, including the mount to the bridge and the panel, was conceptualized, refined, analyzed for structural integrity, and prototyped.
