Abstract
Brazil's vastness and its position as a significant global supplier of commodities make road transportation a crucial aspect of the country's distribution industry. A crucial component of this transportation system is the weighing of loads, which helps in controlling logistics, administration, and safety. Intelligent Transportation and Weighing Systems (ITWS) are becoming increasingly popular in the digitization and modernization of road transportation. However, most weighing stations are in remote areas where access to reliable and cost-effective power sources is limited. Therefore, finding new complementary power sources for these systems is crucial for their effective functioning. In recent years, there has been an increasing emphasis on energy efficiency, sustainability, and decarbonization of power systems. This focus has led to a growing interest in energy harvesting techniques, which generate electricity from ambient energy sources, such as mechanical vibrations and temperature gradients. Such techniques have shown potential as complementary power supplies for weighing systems, particularly in remote locations. This study aims to investigate and compare three types of energy harvesting technologies, including triboelectric, piezoelectric, and conventional electromagnetic generators coupled with a bump, for use as auxiliary power supplies in remote weighing sites. The evaluation was carried out under conditions like those observed on the site to provide accurate and realistic results. Results indicate that although the conventional electromagnetic generator coupled with a bump is three times more expensive than its piezoelectric and triboelectric counterparts, it generates approximately 145 more power per unit of area than the second-place technology. The results of this study provide valuable insights into the most appropriate technology for implementation as an auxiliary power supply on remote weighing sites, thus enhancing the competitiveness of ITWS manufacturers. In addition, the use of energy harvesting techniques to power weighing systems is an eco-friendly approach that can help in achieving the energy efficiency, sustainability, and decarbonization goals of the transportation industry.
