“…Therefore, the main objective of this study is to improve the design parameters of an aeroelastic flutter windbelt with an electromagnetic conversion mechanism. This particular device has shown great development potential and cost effectiveness in terms of manufacturing and maintenance [3,11]. This study fills a research gap by analysing the specifics of low-wind regions and proposing an innovative method to increase wind energy efficiency.…”

“…The study analyses the effects of various factors such as wind speed, wind direction, position of the magnet coil, magnet size and device length on the performance of the flutter-based windbelt for energy generation at low wind speeds. The windbelt proved to be efficient at a wind speed of about 2.7 m/s and generated a peak power of about 5 mW [3]. The development of these micro wind energy systems represents a promising solution for small-scale energy generation and could be a viable alternative to conventional battery-powered microdevices.…”

“…In addition, these turbines require considerable space and are usually located far from residential areas to avoid noise pollution and interference with radar and television reception. Another important consideration is the availability of a wind source with a sufficient cut-in speed [3,4]. Malaysia is in equatorial wind doldrums with the average wind speed less than 4.1 m/s during more than 90% of the total wind hours [5].…”

The need to reduce carbon emissions from conventional electricity generation has led to research into alternative renewable energy solutions, including wind energy. However, conventional wind turbines are not practical in Malaysia due to their size, cost and low wind speeds. Therefore, recent research has focused on the development of small wind energy generation systems, such as wind-induced vibratory devices, for small-scale power generation. This study aims to enhance the design parameters of a flutter-based windbelt with an electromagnetic conversion mechanism specifically tailored to optimise the use of low wind speeds in Malaysia. Various factors such as wind speed, wind direction, magnet position, magnet size and device length were studied to understand their influence on energy generation. The study conducted experiments in controlled and uncontrolled environments, with the latter chosen in a location known for its high wind potential. Five experiments were conducted and measurements were taken three times to ensure accuracy of the data. The results showed that wind speed and magnet size were positively correlated with voltage generation, while wind direction and magnet coil position had more complex relationships. These results contribute to a better understanding of windbelt performance and identify opportunities to optimise windbelt design and placement. Future research could further investigate factors such as turbulence and find ways to integrate the wind belt into more significant devices.

The vehicle suspension system is considered to have tremendous potential in energy harvesting and to be applicable for improving the efficiency of energy use of the vehicle. A novel piezoelectric energy harvester (PEH) with noncontact magnetic force has the feature of low friction loss and is designed based on the vibration characteristic of the suspension system. The research comprises two main components: the motion conversion component and the energy conversion component. A screw-nut mechanism that can convert linear vibration between the vehicle body and the wheel into rotational motion is used as the motion conversion component. The energy conversion component is a core component of the PEH; its function is to convert rotational energy into electrical energy through noncontact magnetic force and piezoelectric effect. The magnetic excitation model's credibility and the modeling method's feasibility are verified by experiment and simulation. Through vehicle field tests, the influence of the driving speed, road surface roughness, and cargo state on the harvested power is obtained. Driving on a random road, the maximum of the generated power is 24.28 W, at 60 km/h, under the laden state. Driving on a pulse road, the harvested power is 3346 W, at 30 km/h, under the unladen state. It is indicated that the PEH is a promising and practical option for harvesting energy for the vehicle's suspension system.
