Abstract

The proposed work gives the details about analysis of properties of piezo electric materials for the selection of material for ultrasonic wave generator. The MATLAB software is used to analyse the characteristics of piezo electric characteristics. The responses are analysed to understand the characteristics and suitability for using the piezoelectric material in ultrasonic wave generator. The responses are obtained by applying impulse input, force and sinusoidal waveform. The quartz crystal is modeled and the inputs, system and outputs are expressed in terms of mathematical equations. The simulation is carried with the help of MATLAB simulink using these mathematical equations related to the piezo electric crystal. The different modes of operations of the crystal are studied to obtain the output. The ultrasonic sensor which uses piezoelectric material to generate ultrasonic waveform is tested and utilized in the distance measuring application. From the analysis of various responses and factors, it is finalized that the quartz crystal is the suitable piezo electric material used in generating the ultrasonic waves. The selection of the material for the ultrasonic wave generator is important to generate ultrasonic wave. The ultrasonic wave generator is initiated by the trigger pulse and generates the ultrasonic wave which is used in various applications and to design intelligent instruments. The proposed work gives an idea about analysis of piezo electric materials for the selection to design intelligent instruments.

Urgent Regarding ISSN Update

Announcement Date: April 20, 2021

Dear Authors and Researchers,
We would like to inform you that the U.S. ISSN Center at the Library of Congress has confirmed that the correct ISSN number of the Journal Psychology and Education is ISSN 1553-6939. This ISSN is to be used instead of ISSN 0033-3077 which is the ISSN that belongs to the former title, “Psychology.” Each time a journal undergoes a major change of title a new ISSN is assigned. Psychology and Education also has been assigned a Linking ISSN (ISSN-L). The ISSN-L is available for use when there is a need to identify and link to a continuing resource without regard to format, for example in services such as OpenURL, library catalogues, search engines or knowledge bases. The next issue of Psychology and Education will be published with ISSN 1553-6969. But the previous ISSN will be also available in the ISSN Portal to retrieve the record for Psychology because it remains the identifier for the former title Psychology and the articles published under that title.
