The advent of energy‐efficient, next‐generation driverless buses places substantial reliance on an array of wireless sensors. In response to this challenge, converting and utilizing these buses' local inertial kinetic energy emerges as a practical strategy for achieving self‐powered capabilities for low‐power appliances. Herein, an inertial energy harvester based on noncontact magnetic force for self‐powered applications in new energy buses is introduced. The harvester system comprises energy capture, mechanical amplification, conversion, and storage modules. The energy capture module proficiently captures and converts the otherwise wasted inertial kinetic energy into magnetic force. The magnified magnetic force produced by the mechanical amplification module efficiently transforms into electrical power within the energy conversion module. Afterward, the alternating current is regulated and stored within the supercapacitor by the energy storage module, achieving self‐powered capabilities for low‐power vehicle appliances. At the same time, combined with the bench test, the maximum output power of the harvester under different vehicle acceleration scenarios is obtained. Taking the campus bus of Liaocheng University as the application object, the average output power of the harvester in the actual operation of the campus is 23.71 mW, which can effectively promote the realization of wireless sensor self‐powered technology in new energy vehicles.

“…However, wireless sensors typically require frequent replacement of their power source and their operational time is limited by the capacity of the batteries. To address these issues, researchers have been exploring the concept of energy harvesting from the sensor's working environment to enable the self-powering of the wireless sensor, as evidenced by previous studies [13][14][15][16][17][18][19][20]. Selfpowered vehicle sensors can be categorized into two types based on the energy sources they utilize: natural environmental energy and in-vehicle energy.…”

The rapid development of internet of things technology has created an urgent demand for wireless sensors. Although wireless sensors have the advantage of widespread use, their applications are limited by power supply. This manuscript proposes a novel magnetically coupled piezoelectric kinetic energy harvester (MPKEH) system to address this issue and enable wireless sensors to be self-powered. The proposed system included four parts: motion capture module, motion transformation module, energy transformation module, and power storage module. The motion capture module, a single-pendulum, is selected to convert the vehicle’s inertial energy into the mass ball kinetic energy. The motion transformation module, which includes a double-directional rectification mechanism and a mechanical speed-up mechanism, converts two-way rotations into one-way rotations and increases rotation speed. Piezoelectric material is frequently bent in the energy transformation module to generate alternating current (AC). The power storage module rectifies AC into direct current and stores the power in the super-capacitor, which supplies power to the electrical equipment. The velocity of the mass ball under five realistic bus driving cycles is obtained using multi-body dynamics software and Simulink. Experiments revealed that the average output power of the system could be as high as 2.4 W. Charging capacitors of 100 µF, 220 µF, 470 µF, and 1000 µF to 2 V using the MPKEH system takes 25 s, 49 s, 70 s, and 238 s, respectively. In the conducted experiments using the Liaocheng University campus bus, the maximum average power output reached 1.97 W. These results suggest that the MPKEH system can effectively self-supply energy for low-power appliances in new energy buses.

“…In the end, many kinds of energy harvesters have been tested and implemented in recent years to be used in monitoring systems with the aim to recharge batteries when an energy excess is produced [23][24][25][26][27]. Among them, solar energy is seen as the most reliable and widely available in outdoor scenarios [28,29].…”

Nowadays, railway freight transportation is becoming more and more crucial since it represents the best alternative to road transport in terms of sustainability, pollution, and impact on the environment and on public health. Upgrading the potentiality of this kind of transportation, it would be possible to avoid delays in goods deliveries due to road accidents, traffic jams, and other situation occurring on roads. A key factor in this framework is therefore represented by monitoring and maintenance of the train components. Implementing a real time monitoring of the main components and a predictive maintenance approach, it would be possible to avoid unexpected breakdowns and consequently unavailability of wagons for unscheduled repair activities. As highlighted in recent statistical analysis, one of the elements more critical in case of failure is represented by the brake system. In this view, a real time monitoring of pressure values in some specific points of the system would provide significant information on its health status. In addition, since the braking actions are related to the load present on the convoy, thanks to this kind of monitoring, it would be possible to appreciate the different behavior of the system in case of loaded and unloaded trains. This paper presented an innovative wireless monitoring system to perform brake system diagnostics. A low-power system architecture, in terms of energy harvesting and wireless communication, was developed due to the difficulty in applying a wired monitoring system to a freight convoy. The developed system allows acquiring brake pressure data in critical points in order to verify the correct behavior of the brake system. Experimental results collected during a five-month field test were provided to validate the approach.
