Abstract: Our group aims to produce sustainable energy using piezoelectric crystal pads. “Power harvesting” from vibrations of the piezoelectric substances is the topic of latest research. In our paper we intend to theoretically shed light on the feasibility regarding the use of piezoelectric crystals for generation of energy for meeting the future energy requirements. We are proposing two methods for the use of piezoelectric pads for energy development harnessing the huge pressure gradient available in the ocean waters. In our first model we propose the installation of piezoelectric crystal mats in sea beds at suitable depth meeting the requirements of the pressure needed for the development of appreciable amount of voltage in the crystals. In second model we propose to install slanted piezoelectric assemblies at the sea shore to produce pressure difference by incoming waves.
them when piezoelectric material is subjected to some mechanical force it generates an electrical voltage and when an electric voltage is applied it undergoes deformation. Piezoelectric energy harvesting means generating energy using the pressure from the environmental energy. It makes use of the direct piezoelectric effect. It means that deformation of the piezoelectric material is used for generating energy. When a piezoelectric material is pressed or pulled in the direction of its thickness generation of energy occurs. Due to the distortion of the lattice structure an electric charge is produced on the surface of the piezoelectric material. For example: A 1 cm3 cube of quartz with 2 kN (500 lbf) of correctly applied force can produce a voltage of 12500 V. Owing to these characteristics piezoelectric materials can be used as a sensor, an actuator, as well as a power generation unit.
