dc.description.abstractA "world system" for "the transmission of electrical energy without wires" that depends upon the electrical conductivity was invented by Nikola Tesla in the early 1900s. From the idea, it triggered researchers to develop methods for moving electrical energy over “distances” without wires. Wireless is rapidly gaining in popularity for both home and business networking and this technology is continues to improve. For the reason that there exist situations where interconnecting wires are inconvenient, hazardous, or impossible, thus making wireless transmission useful and essential. Piezoelectric actuators are devices that convert electric energy into a mechanical motion. With their compact size, high precision positioning and low power consumption, piezoelectric actuators are being used in an ever-growing number of fields outside conventional usage. In most applications, electric energy is applied to piezoelectric actuators via lead wires soldered on the electrodes of piezoelectric components. [1] In this study, a new technique of wirelessly transmitting electric energy to piezoelectric components is explored. It focuses on possible experiments that make used on the principle of coupling of an electromagnetic wave and mechanical vibration in the piezoelectric components to obtain maximum output power. This project is an entirely hardware-based project that design systems that would be able to obtain maximum output power. Brief explanations on the piezoelectric materials and the principle of piezoelectricity will be illustrated to allow readers to gain a better understanding in the experiments involved.en_US
