Piezoelectric energy has been recently paid attention in the field of alternative energy. Day by day the traditional energy sources including Coal tar and oils are becoming scarce. People are heading to an alternative energy source to meet the future energy demand. Piezoelectric energy is one of the competitive energy sources compared to the conventional renewable energy sources including solar, wind, and geothermal power and so on. This energy production method bears enormous research potential because it can be used as the roadway for a new method of power generation. This research project aimed to identify which shaped wafer-box produced the higher electricity. This research project utilized both a 3-D printer and a 3-D Computer Aided Design (CAD) to develop five different shapes of prototype wafer boxes coupled with piezoelectric sensors. Various forms were developed see if there were any potential difference in power (voltage) generation due to the structure of the box. In order to run an Asphalt Pavement Analyzer (APA) wheel load test, piezoelectric ceramic disk sensor was embedded into the wafer box. Collected data from the APA load wheel test were analyzed using various statistical methods which produced significant findings. The analytical result indicated that out of the five different shaped wafer boxes the circularly shaped box produced the highest average voltage values. The triangular shape is in the second position to produce voltage. The square shape is in the lowest position of the list to produce electricity. The 3-D printers can print wafer-box with other different materials for testing. The 3-D printer can print the product accurately which gives the more reliable output. These 3-D printed wafer-boxes could be can be utilized for APA testing to determine the effectiveness. Additional research could lead to a broader understanding of PZT-based energy harvesting technology as well as providing a platform for testing PZT harvest units.
