Magnetostriction and its Application to Engineering Devices 

Magnetostriction is a phenomenon in which magnetization of a magnetic material changes its dimensions and plays an important role in the study of physical properties of ferromagnetic materials. Familiar examples of magnetostriction phenomena are well known, such as the buzzing sound near a transformer and the cause of reduced efficiency in motors and other electrical equipment. 

This presentation will summarize and discuss the effective use of magnetostriction phenomena. Among ferromagnetic materials, those with large dimensional change due to magnetostriction are called magnetostrictive materials, and typical magnetostrictive materials are first organized and explained. Next, various devices such as vibration actuators using magnetostrictive materials and stress sensors and torque sensors using magnetic anisotropy sensors based on magnetostrictive phenomena are devised and put into practical use.

Magnetic Application: Contribution to Oil Palm Industry 

The application of electromagnetic and magnetic technology can significantly enhance various aspects of the palm oil industry. These technologies can power machinery used in harvesting processes, such as palm fruit harvesters and threshers, by developing high torque motors. This not only improves efficiency but also reduces labor requirements.

Inside palm oil plantations, for the fruit evacuating process, high power density generators combined with batteries can be utilized to provide the necessary power output in a compact and lightweight design, making them ideal for transportation applications.

Moreover, magnetic and electromagnetic sensing technologies can be employed for maturity sensing in palm oil fruits. By analyzing the fruits' electromagnetic properties, such as moisture content and oil composition, these technologies can determine the optimal time for harvesting, ensuring high-quality oil production.

Additionally, autonomous robotics powered by high torque motors can perform various tasks in the palm oil industry, including planting, pruning, and harvesting. These robots can operate autonomously, reducing the need for manual labor and improving overall efficiency.

Overall, the development and implementation of these technologies can significantly enhance the efficiency, productivity, and sustainability of the palm oil industry.
