In this paper, we present a Solar Energy harvesting and storing system. The solar energy is converted to electric charge by photosensitizing film and the charge generated is stored between the upper membrane and lower membrane of a capacitor. A PZT material based capacitor is used to retain the charge. The proposed system not only harvest energy from solar sources but also stores the charge bot...

Some nondestructive techniques of the Structural Health Monitoring (SHM) have improved their analysis in past decades. Among them, electromechanical impedance-based SHM technique (EMI-SHM) has been tested several fields and associated to different statistical methodologies. Considering nature spatial variation damage metric data along structures, herein is proposed use indicator kriging method ...

We report on the first successful operation of a cyclic contact scanning force microscope ~SFM! using a self-excited cantilever in liquid. Based on a new structure including a PZT reference pattern and a free-standing PZT cantilever, the piezoelectric self-excitation and self-detection mechanism for a PZT microcantilever was developed successfully. The topography is recorded by measuring the pi...

Utilizing plasmonic nanostructures for efficient and flexible conversion of solar energy into electricity or fuel presents a new paradigm in photovoltaics and photoelectrochemistry research. In a conventional photoelectrochemical cell, consisting of a plasmonic structure in contact with a semiconductor, the type of photoelectrochemical reaction is determined by the band bending at the semicondu...

Pyroelectric harvesters convert time-dependent temperature variations into electric current. The appropriate geometry of the pyroelectric cells, coupled with the optimal period of temperature fluctuations, is key to driving the optimal load resistance, which enhances the performance of pyroelectric harvesters. The induced charge increases when the thickness of the pyroelectric cells decreases. ...

A combination of vertical and lateral piezoresponse force microscopy ~VPFM and LPFM, respectively! has been used to map the out-of-plane and in-plane polarization distribution, respectively, of ~111!-oriented Pb(Zr,Ti)O3-based ~PZT! ferroelectric patterned and reactively-ion-etched capacitors. While VPFM and LPFM have previously been used to determine the orientation of the polarization vector ...

This paper presents a study of lead zirconate titanate (PZT) films hydrothermally grown on a dome-shaped titanium diaphragm. Few articles in the literature address the implementation of hydrothermal PZT films on curved-diaphragm substrates for resonators. In this study, a 50-μm-thick titanium sheet is embossed using balls of designed dimensions to shape a dome-shaped cavity array. Through singl...

Lead zirconate titanate (PZT) nanofibers are obtained by electrospinning a sol–gel based solution and polyvinyl pyrrolidone (PVP) polymer, and by subsequent sintering of the electrospun precursor fibers. The average diameter of the precursor PZT/ PVP green fibers has increased with the aging of the precursor solution along with an increase in the viscosity. Bead-free uniform green PZT/PVP fiber...

Processing effects on the dielectric properties of sol–gel-derived PbZrO3–PbTiO3 (PZT) films integrated onto Pt/Ti/SiO2//Si substrates are reported. Sol–gel synthesis and deposition conditions were designed to produce films of varying thickness (95–500 nm) with consistent chemical composition (Pb (Zr0.53Ti0.47)O3), phase content (perovskite), grain size (B110 nm), crystallographic orientation (...
