Development of Piezoelectric as One of the alternatives for Marine Wave Energy in Indonesia

Abstract

As one of the tools in the field of Energy Production, Piezoelectric is one of the most reliable and efficient system on the renewable energy. These systems holds many potential for reducing the consumption of oil and gas energy because the system will generate electricity from natural resources. For piezoelectric materials when pressed, the atomic structure inside the material will change, and thus cause the formation and spate of the dipole moment. This formation will produce changes especially in the voltage differences across piezoelectric materials. This process is called a direct piezoelectric effect. Piezoelectric materials can be integrated into the system without difficulty. This is because the material will not have moving parts, so it will not require frequent maintenance. Moreover, the piezoelectric also has the potential capability to change and convert into the electrical energy that came from strain energy applied to the system. Those converting process also could be done with direct motion and no addition at all. In addition, the material is also capable of producing power at a certain level of stress that can be easily conditioned and achieved. When using the piezoelectric material, it is usually consist of various object that have the mass that also installed to a spring, silencer and also another model as its structure. Those installaion will operates when the object itself have an external resonant frequency that could came from various sources, the results of those frequency will make the model move into a linear motion and will create energy to be accessed by another process.. The objective of the study was to find out whether the application of Piezoelectric is suitable for Renewable Sea Energy in Indonesia using wave-to-wire modeling technique.
