Abstract: Lead-free, high piezoelectric performance, Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 (BZT-0.5BCT) sub-micron powders with perovskite structure were fabricated using the sol-gel process. A 0-3 type composite was obtained by choosing epoxy resin as mat... see more

Existing studies on elastic waves in periodically laminated piezoelectric structures mainly concerned the passive band properties, since the electrical boundaries in the considered structures cannot vary. This paper investigates the tuning of band propert... see more

This paper describes a double-layer simplified sensor unit based on the interesting electromechanical properties of MWNT mixed by polymer composite and PVDF films, which is envisaged to imitate the distributed tactile receptors of human hands so as to hel... see more

The monitoring of a structure (e.g., a building) enables safe utilization of such a structure. A large number of sensors that measure selected parameters are often required in applied monitoring systems. Cables or batteries are used to power such sensors.... see more

Low velocity impact induces barely visible damage in the form of matrix cracking or delamination that can grow under hydro-thermo-mechanical loading and possibly lead to catastrophic failure if not detected at an early stage. A network of piezoelectric tr... see more

This work aims to improve pedestrian functions, improve the welfare of waste banks and scavengers, and fulfil electricity needs for the surrounding community towards Society 5.0. The method of writing is done with secondary data through the latest literat... see more

The lead zirconate titanate (PZT)-graphite piezocomposites have potential for higherpiezoelectric sensitivity, lower acoustic impedance, higher piezoelectric voltage constants, higherelectromechanical coupling coefficient, and higher hydrostatic coefficie... see more

The acoustics is interpreted as the science that studies sound waves, vibrations and their interactions with the environment, in both macroscopic and microscopic systems. This paper presents the model of piezoelectric acoustic detector developed with the ... see more

The effect of the polarization orientation in the piezocomposites global characteristic has been studied and published. This work is inspired in this idea. In the present work, the effects of the magnetization orientation related to the effective properti... see more
