Investigation of Ferroelectricity and Piezoelectricity in Polar and Non-polar Polymers
(2022-06-01)
An overview is presented of experimental investigations during two decades at the Polymer Group Prof. Bernhard Gross in Sao Carlos, Brazil, on the properties of piezoelectric polymers. The paper is focused on innovations ...
Evaluation of the piezoelectric behaviour produced by a thick-film transducer using digital speckle pattern interferometry
(Elsevier, 2011-02)
This paper presents an interferometric measurement of the out-of-plane deflections produced by a piezoelectric transducer, manufactured by thick-film deposition of a ceramic paste over an alumina substrate, when is subjected ...
Effect of parametric uncertainties on the performance of a piezoelectric energy harvesting device
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2012)
The use of piezoelectric materials for the development of electromechanical devices for the harvesting or scavenging of ambient vibrations has been extensively studied over the last decade. The energy conversion from ...
Piezoelectric, elastic, Infrared and Raman behavior of ZnO wurtzite under pressure from periodic DFT calculations
(2017-03-01)
The influence of pressure on elastic, piezoelectric (total and clamped-ion contribution), dielectric constants, Infrared and Raman spectra, and topological properties of ZnO wurtzite structure was carried out via periodic ...
