Journal ArticleDOI
Connectivity and piezoelectric-pyroelectric composites
TL;DR: In this article, a series and parallel model for composite piezoelectric and pyroelectrics is presented, which leads to several interesting results, such as a diphasic pyroelectric in which neither phase is pyrocharged.
Journal ArticleDOI
Electrical Resistivity of Composites
TL;DR: In this paper, a general effective media (GEM) equation, which combines most aspects of both percolation and effective media theories, is introduced, and the GEM equation quantitatively fits electrical resistivity (conductivity) as a function of the volume fraction data for binary composites.
Journal ArticleDOI
Materials for high temperature acoustic and vibration sensors: A review
TL;DR: In this article, the authors compared various commercial methods and materials for acoustic transduction, identifying their advantages and limitations, and concluded that the piezoelectric approach offers several advantages, including design cost and simplicity.
Journal ArticleDOI
Structural basis of ferroelectricity in the bismuth titanate family
TL;DR: More than fifty ferroelectrics belong to the Bi4Ti3O12 family, and all consist of Bi2O2 layers interleaved with perovskite-like Mn−1RnO3n+1 layers.
Journal ArticleDOI
Piezoelectric Sensors and Sensor Materials
TL;DR: A review of the current trends and historical development of piezoelectric sensors and sensor materials technology can be found in this paper, where a discussion of the bases of piezo and ferroelectric activity is discussed.
