Piezoelectric softening by Nb substitution in (Ba,Pb)ZrO
Nava Setter, Nicola Marzari, Dragan Damjanovic, Alberto Biancoli, David Bahati
Donor doping is commonly applied for softening of the piezoelectric and dielectric properties and facilitation of polarization switching in the ubiquitous Pb(Zr,Ti)O-3 [PZT] ceramics. The origin of the donor-dopant effects is not entirely clear. (Pb,Ba)ZrO ...
Wiley-Blackwell2017A concept of wireless and passive very-high temperature sensor
Paul Muralt, Ramin Matloub Aghdam, Andrea Mazzalai
There is a need for sensors capable operating at temperatures above 1000 degrees C. We describe an innovative sensor that might achieve this goal. The sensor comprises two main elements: a thermocouple and a surface acoustic wave (SAW) strain sensor. The c ...
Amer Inst Physics2017Domain Pinning: Comparison of Hafnia and PZT Based Ferroelectrics
Even though many studies on the field cycling behavior of ferroelectric hafnium oxide have recently been published, the issue is still not fully understood. The initial increase of polarization during first cycles is explained by different theoretical and ...
Wiley2017Domain walls and defects in ferroelectric materials
The results of recent studies of domain walls and their interaction with defects in BaTiO3, Pb(Zr, Ti)O-3, and BiFeO3 are discussed. The studies reveal why donor- and acceptor-doped Pb(Zr, Ti)O-3 behave differently, what is the role of stationary charged d ...
Japan Society of Applied Physics2017Green paper-based piezoelectronics for sensors and actuators
Danick Briand, Etienne Pierre Lemaire, Christopher John Borsa
We report a novel biodegradable piezoelectric composite fabricated from paper and the piezoelectric salt, sodium potassium tartrate tetrahydrate (Rochelle salt, which we term PiezoSalt). The piezoelectric composite is non-toxic and is fabricated free of en ...
Elsevier2016Piezoelectric Coefficients of AlScN Thin Films in Comparison
Paul Muralt, Ramin Matloub Aghdam, Mahmoud Hadad
Since the discovery of a high piezoelectric response in AlScN by Akiyama and coworkers in 2009, a number of works of other groups confirmed the large increase of piezoelectricity when partially substituting Al cations by Sc cations, as long as the alloy gr ...
Ieee2016Characterization and Fatigue of the Converse Piezoelectric Effect in PZT Films for MEMS Applications
Paul Muralt, Ramin Matloub Aghdam, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma
A measurement setup for the detailed study of the transverse piezoelectric coefficient e(31,f) in the converse (actuator) mode was developed. It allows the assessment of the piezoelectric stress in thin films on silicon cantilevers and provides for a corre ...
Institute of Electrical and Electronics Engineers2015Converse mode piezoelectric coefficient for lead zirconate titanate thin film with interdigitated electrode
Paul Muralt, Ramin Matloub Aghdam, Robin Nigon, Silviu Cosmin Sandu, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma
The use of interdigitated electrodes (IDEs) in conjunction with ferroelectric thin films shows many attractive features for piezoelectric MEMS applications. In this work, growth of {1 0 0}-textured lead zirconate titanate (PZT) thin films was achieved on i ...
Institute of Physics2015Green piezoelectric for autonomous smart textile
Danick Briand, Etienne Pierre Lemaire, Christopher John Borsa
In this work, the fabrication of Rochelle salt based piezoelectric textiles are shown. Structures composed of fibers and Rochelle salt are easily produced using green processes. Both manufacturing and the material itself are really efficient in terms of en ...
Iop Publishing Ltd2015Nano-SAW devices for RFID and sensing applications: study of lithium niobate behavior
Andrea Lozzi, Seïfeddine Mounir Ben Khelil
The key element of a SAW device is the piezoelectric material that allows conversion between electrical and mechanical energy. Lithium niobate is an appealing material as it could potentially provide high efficient SAW devices. This material is strongly an ...
