Guided waves generated by a spatially distributed array of piezoelectric are being evaluated by many researchers for structural health monitoring applications. These surface-mounted transducers, which are typically Lead Zirconate Titanate (PZT), are generally assumed to be both undamaged and properly bonded to the host structure during usage. However, this assumption may not be valid, particula...

Lead zirconate titanate (PZT) has been widely used because of its electrochemical effect, but effect on soil microorganisms is rarely studied. In this study, laboratory microcosms with different moisture content and pH were established to explore the effects PZT-5H bimorph quantities states after 49 days. Plate counting was study number changes bacteria, fungi actinomycetes. Isothermal microcal...

Ž . Ž . The microstereolithography mSL of lead zirconate titanate PZT thick films on platinum-buffered silicon substrates is reported for Ž . the first time in this paper. Crack-free PZT thick films 80–130 mm thick have been fabricated by laser direct-write UV polymerization from the HDDA-based UV curable PZT suspensions. The characterization of the fired films shows dielectric permittivities o...

In this study, we demonstrated the magnetoelectric control of magnetic thin films. (111)-textured Pd/Ni/ Pd thin films were prepared on mica/lead zirconium titanate (PZT) substrates for the investigation. The reversible modulation of magnetic coercivity in Ni films was observed through the electric-voltagecontrolled strain variation from the PZT substrate. For 14 nm Ni film, the applied electri...

This paper proposes a novel flexible piezoelectric micro-machined ultrasound transducer, which is based on PZT and a polyimide substrate. The transducer is made on the polyimide substrate and packaged with medical polydimethylsiloxane. Instead of etching the PZT ceramic, this paper proposes a method of putting diced PZT blocks into holes on the polyimide which are pre-etched. The device works i...

This paper presents a micro-fabricated flexible and curled PZT [Pb(Zr0.52Ti0.48)O3] cantilever using d33 piezoelectric mode for vibration based energy harvesting applications. The proposed cantilever based energy harvester consists of polyimide, PZT thin film, and inter-digitated IrOx electrodes. The flexible cantilever was formed using bulk-micromachining on a silicon wafer to integrate it wit...

We describe the characterization, ferroelectric phase stability and polarization switching in strain-free assemblies of PbZr0.3Ti0.7O3 (PZT) nanostructures. The 3dimensionally ordered macroporous structures present uniquely large areas and volumes of PZT where the microstructure is spatially modulated and the composition is homogeneous. Variable temperature powder X-ray diffraction (XRD) studie...

In this paper, a linear actuator for precision positioning of dual objects is proposed based on a double friction drive principle using a single piezoelectric element (PZT). The linear actuator consists of an electromagnet and a permanent magnet, which are connected by the PZT. The electromagnet serves as an object 1, and another object (object 2) is attached on the permanent magnet by the magn...

Known ultrasonic transducers for simultaneous generation of longitudinal and shear waves are reviewed: quartz and lithium niobate crystals tilted CdS and ZnO films. A special attention is devoted to the rotated cuts of PZT piezoceramics, literature data theoretical background conclusions are analysed. Manufacturing technology of dual mode PZT transducers with different cut angles and thickness ...

We proposed and demonstrated a novel practical fiber Bragg grating (FBG) fabrication setup constructed with high performance linear stages, piezoelectric translation (PZT) stages, and a highly stable continuous wave laser. The FBG fabrication system enables writing of long FBGs by a continuous translate-and-write process and allows implementation of arbitrary chirp and apodization. A key innova...
