“…Transportation in smart cities, like nerves in the human body, not only deliver things but also information. Various energy harvesters integrated into roads, bridges or railways, and equipped on vehicles or trains have been reported by applying TENG [264][265][266][267] and PENG [268][269][270], in which vibrations and impacts are converted into electric power to support electronics monitoring transportation. Along with further signal processing, selfpowered sensors developed from energy harvesting technologies also provided crucial information for safety monitoring and early warning.…”

“…Based on the positive piezoelectric effect of piezoelectric materials [9,10], piezoelectric energy harvesters (PEHs) can convert this kinetic energy into electrical energy (5). The developed PEHs can be utilized to power low-power sensors for traffic flow monitoring [11], structural health monitoring [8], and vehicle weight estimation [12], as well as to power electronics, such as signals, lights, and Internet of things systems [13,14]. Furthermore, research indicates that PEH technology has technical advantages, such as a low environmental impact, high energy density, and around-the-clock service, and could be the leading technology in green and intelligent roads [15].…”

To advance the development of piezoelectric energy harvesters, this study designed and manufactured bridge-unit-based and pile-unit-based piezoelectric devices. An indoor material testing system and accelerated pavement test equipment were used to test the electrical performance, mechanical performance, and electromechanical coupling performance of the devices. The results showed that the elastic modulus of the pile structure device was relatively higher than that of the bridge structure device. However, the elastic modulus of the two devices should be improved to avoid attenuation in the service performance and fatigue life caused by the stiffness difference. Furthermore, the electromechanical conversion coefficients of the two devices were smaller than 10% and insensitive to the load magnitude and load frequency. Moreover, the two devices can harvest 3.4 mW and 2.6 mW under the wheel load simulated by the one-third scale model mobile load simulator, thus meeting the supply requirements of low-power sensors. The elastic modulus, electromechanical conversion coefficients, and electric performance of the pile structure device were more reliable than those of the bridge structure device, indicating a better application prospect in road engineering.

In this study, a dual-piezoelectric energy harvesting system with contact and non-contact characteristics was driven by a cantilever beam. The harvester performance of the multipoint energy harvesting system driven by cantilever-beam vibration was designed, detailed analysis and optimization strategies were developed, and its application in the security field was successfully demonstrated. Herein, we provide theoretical guidance for the design of the dual-piezoelectric energy harvesting. We designed and fabricated a prototype of the dual-piezoelectric energy harvesting. A test system was designed and constructed. The relationships among the distance and frequency of the two piezoelectric acquisition mechanisms and the open-circuit voltage were investigated. Additionally, the effects of different loads on the output power were examined. The peak power reached 10.12 mW under a gravitational acceleration of 1g. The analysis indicated that the dual-piezoelectric energy harvest device has a higher energy harvest efficiency than the singlepiezoelectric energy harvest device. Owing to the multipoint harvest strategy, even if a generator suddenly deteriorates or fails, the entire system can maintain a certain power output, which is more commercially feasible. The results of this study indicate that the output of the piezoelectric energy harvesting is stable and reliable and that the output energy satisfies the requirements for a safety warning device.
