The concept of green and sustainable development is driving the convergence of transportation systems and energy technologies. New energy harvesting technology is an important way of the development in the green intelligent transportation system. Comparing with the power supply via batteries or cables, it has the advantages of convenient, sustainable, green and low carbon to harvest mechanical energy from the traffic environment and convert it into electrical energy to power the widely distributed small electromechanical systems. There are many studies on mechanical energy harvesting in traffic environment, few of them have comprehensively discussed these studies and their applications in the intelligent transportation. This paper first outlines the principles, methods, and energy management strategies of the mechanical energy harvesting in the traffic environment. The advantages, disadvantages, and applicability of various energy harvesting technologies are comprehensively and systematically analyzed from vehicle and road dimensions. The applications of energy harvesting technology was discussed includes: self-powered traffic control, self-powered vehicle-road collaboration and self-powered health monitoring of traffic infrastructure. Finally, the challenges and prospects of mechanical energy harvesting technology and applications in the traffic environment are discussed. Mechanical energy harvesting in traffic environment has broad application prospects in intelligent transportation, while improving the output power and reliability of the energy harvesting system is the key to its wide application in intelligent transportation systems.

“…To get the maximum energy transfer from the vibrator (rocker) to the rotating load (crank), the motion of the vibrator and rotating load must be synchronized, although the tuning approach for this synchronization is left to be studied in future work. A novel self-tuning concept of harvesting and converting vibration energy is presented by Gunn et al (2021) [31]. By transferring energy through a variable distance of magnet force, a non-linearity will exist in energy flow, which effects the dynamic performance of the system.…”

Objective: In this paper, a proposed technique of motion transmission is introduced, which is based on the crank-rocker principle of motion. The energy transmission action is performed through magnetic force, in which no direct connection is made between the energy source input and the energy load output. Also, to illustrate the concept of motion and to approve the continuity of energy transmission using this proposed technique, a simple model of this mechanism has been built and run, showing the basic sequence of operation. Methodology/analysis: In this mechanical transmission mechanism, one side is rotating and the other side is vibrating, in which any side is energy input (which is usually the vibrating rocker), and the other side is energy output (which is the rotating crank). That seems similar to the classical crank-rocker machine in the four-bar mechanism, but without direct mechanical contact between the input and output energy stream. The concept of motion and mathematical analysis with structuring conditions is provided in this paper, where the dynamic analysis of the system is left for future work. A pilot physical prototype is manufactured and experimentally tested, validating the proposed design. Findings: The structural parameters of this proposed contactless crank-rocker machine have been modelled and simulated using the MATLAB program. It shows that these parameters could be selected and optimized to guarantee the minimum conditions for continued energy transmission. Based on these parameters, a simple model has been built and operated, which illustrates the concept of motion and validates the finding of MATLAB simulation. Novelty/improvement:Contactless crank-rocker motion is a very promising technique. It is possible to apply it in many applications, like the energy harvesting area, and it could be employed certainly in specific designs, such as MEMS, where no other motion transmission types can be used.

Energy harvesters have gained popularity as green energy devices that transform mechanical energy from the environment into electricity. However, traditional piezoelectric energy harvesters are limited by narrowband response, and the output capability of electromagnetic energy harvesters is dependent on the rate of magnetic field changes on the coil, which is constrained by the device’s structure. To address these issues, this paper presents a hybrid energy harvester (HEH) that combines coils and arc magnets, forming an electromagnetic component (EMEH). Additionally, it incorporates a piezoelectric cantilever beam (PECB) as a piezoelectric component (PEH). Unlike traditional electromagnetic energy harvesters, this design utilizes two arc magnets to drive the rotating brackets, thereby achieving the opposite movement of the coil and magnet. This increases the relative velocity and consequently enhances the rate of magnetic field change on the coil. Simultaneously, it achieves frequency up-conversion by inducing vibration in the PECB through magnetic force. Under an external excitation of 5.5 Hz, the PEH achieves a maximum power of 0.362 mW at a load resistance of 330 kΩ, while the EMEH with 1200 turns of coil attains a maximum power of 8.74 mW at a load resistance of 110 Ω. The power density of the PEH reaches 94.96 μW cm−3. These results highlight the significant potential of the proposed energy harvester for powering low-power devices.
