The field of transportation plays a crucial role in the development of society. It is vital to establish a smart transportation system (STS) to increase the convenience and security of human life. The incorporation of artificial intelligence (AI) and the Internet of Things (IoT) into the traffic system has facilitated the emergence of innovative technologies like autonomous vehicles or unmanned aerial vehicles (UAVs), which contribute to the reduction of traffic accidents and the liberation of human driving time. However, this improvement involves the use of multiple sensor devices that need external power sources. As a result, pollution occurs, as do increases in manufacturing costs. Therefore, the quest to develop sustainable energy remains a formidable obstacle. Triboelectric nanogenerators (TENG) have emerged as a possible solution for addressing this problem owing to their exceptional performance and simple design. This article explores the use of TENG-based self-power sensors and their potential applications in the field of transportation. Furthermore, the data collected for this study might aid readers in enhancing their comprehension of the benefits linked to the use of these technologies to promote their creative ability.

The purpose of this paper is to design an energy harvester to improve output performance. The theoretical analysis of the piezoelectric energy harvester has been performed. Reducing the length of one cantilever beam, thereby changing the relative impact position, causing the amplitude of the two cantilever beams to be different, and making the waveform of two beams different. Some experiments have been tested to verify the feasibility of the device and compare the differences with Plan A. Based on the experiment, it can be concluded that the output voltage is higher at both high and low speeds. When the rotation speed is 255 r min−1, Plan B arrives at the optimum speed, and the maximum output voltage is 166.2 V, which significantly increases from 97.2 V of Plan A. The maximum output power is 0.966 W under the load resistance of 10 kΩ. The maximum voltage is 157.7 V under the load resistance of 120 kΩ. Nevertheless, the maximum voltage and maximum power of Plan A are 92.62 V and 0.52 W. Besides, the prototype has fewer materials and nearly 1.5 times the energy conversion rate compares to Plan A. It can light up 42 LEDs easily and can adapt to environmental vibration frequency changes, so it has an intensely adaptable and outstanding performance in practical applications.

“…Khameneifar [10] proposed a method to enhance the output characteristics of the rotational harvester by using the cantilever tip mass; and the experimental results show that the power output is 6.8mW at 138 rad/s. He et al [11] proposed a system that could generate high output voltage in low-frequency rotation based on nonlinear magnetic coupling and contact frequency conversion mechanism. Fang et al [12,13] investigated a collision harvester with softening effect, and the maximum output power can be increased by 135% at 11.5 Hz, but long-term impact and collision would damage the piezoelectric oscillator.…”

Bi-stable piezoelectric-magnetic-elastic energy harvester (BPEH) has been widely investigated to improve the harvesting performance of low-frequency vibration energy. The centrifugal effect, gravity effect and bi-stable restoring effect and their combinations on the BPEH's potential wells and dynamic behaviors in rotational motions are completely different from those in low-frequency ambient vibrations, and they have not yet been well explored. This article presents a rotational bi-stable piezoelectric-magnetic-elastic energy harvester (R-BPEH) to enhance the rotational vibration energy harvesting with the combinations of the centrifugal effect, gravity effect and bi-stable restoring effect. A theoretical model considering the centrifugal effect, gravity effect and bi-stable restoring effect was established to describe the dynamic response behaviors of the R-BPEH. The centrifugal effect caused by the centrifugal force, gravity effect induced by the gravity of tip magnet, bi-stable restoring effect induced by the nonlinear magnetic force and their combinations on the potential energy wells, dynamic performance and power generation are theoretically explored under different system parameters, such as magnetic distance, rotating radius and rotational speed, etc. The results show that the centrifugal hardening stiffness induced by the centrifugal force of the R-BPEH can increase the oscillating frequency and harvesting voltage in high rotational speed range, but narrows the working bandwidth of inter-well motion; The gravity component in transverse direction generates additional periodical excitation force on the R-BPEH to produce high energy generations, the gravity component in axial direction softens the centrifugal hardening effect to enhance the energy generation in low rotational speed range. In addition, their combination leads to the appearances of asymmetric potential wells which further enhance the dynamic and electrical performances of the R-BPEH. Experiments are conducted to show good agreement with the theoretical results. The maximum harvested voltage and power generation of the R-BPEH achieves 2.5 V and 0.59 µW when the rotational speed ranges from 150 rpm to 540 rpm.
