“…Alternative models may provide specific boundaries, within which specific constants may be defined and utilized to solve equation (13). For example, the W. Ellison model provides the following constants for a frequency in the range between 3 and 40 GHz, temperature between -2 °C and 30 °C, and salinity between 20 and 40 parts per thousand [5].…”

“…The next type of piezoelectric material is thin-film piezoelectric materials. These materials are considered ideal for energy harvesting acoustic vibrations and can be utilized as microelectromechanical system energy harvesters for such things as gyro-sensors or information processing and radio frequency devices on microchips [12,13]. Some thin-film piezoelectric materials include perovskite materials fabricated through various material treatment processes like annealing, ablation, or sintering [13].…”

“…For example, the composites typically used as the transducers have high values of k for better energy conversion, a value that is also preferred to be as close to 1 as possible for the piezoelectric material as well. In addition to k, the electromechanical coupling coefficient, impedance should also be tailored to match between the two devices to ensure better sensitivity [11][12][13][14].…”

This paper provides a comprehensive review on transducer technologies for underwater communications. The popularly used communication transducers, such as piezoelectric acoustic transducers, electromagnetic acoustic transducers, and acousto-optic devices are reviewed in detail. The reasons that common air communication technologies are invalid die to the differences between the media of air and water are addresses. Because of the abilities to overcome challenges the complexity of marine environments, piezoelectric acoustic transducers are playing the major underwater communication roles for science, surveillance, and Naval missions. The configuration and material properties of piezoelectric transducers effects on signal output power, beamwidth, amplitude, and other properties are discussed. The methods of code and decode communication information signals into acoustic waves are also presented. Finally, several newly developed piezoelectric transducers are recommended for future studies.

A Brief Introduction and Current State of Polyvinylidene Fluoride as an Energy Harvester

et al. 2022

View full text Add to dashboard Cite

This review summarizes the current trends and developments in the field of polyvinylidene fluoride (PVDF) for use mainly as a nanogenerator. The text covers PVDF from the first steps of solution mixing, through production, to material utilization, demonstration of results, and future perspective. Specific solvents and ratios must be selected when choosing and mixing the solution. It is necessary to set exact parameters during the fabrication and define whether the material will be flexible nanofibers or a solid layer. Based on these selections, the subsequent use of PVDF and its piezoelectric properties are determined. The most common degradation phenomena and how PVDF behaves are described in the paper. This review is therefore intended to provide a basic overview not only for those who plan to start producing PVDF as energy nanogenerators, active filters, or sensors but also for those who are already knowledgeable in the production of this material and want to expand their existing expertise and current overview of the subject.
