Processing and Characterization of Piezoelectric Materials into MicroElectroMechanical Systems

The Pb(Zr, Ti)O3 (PZT) based micro electro mechanical systems are presented. Piezoelectric effect, basic piezoelectric equations are explained. Lost silicon mold process for PZT microstructures, PZT thin film deposition, and PZT based piezoelectric micromachined switch device are discussed.

Characterization of piezoelectric materials using ultrasonic and resonant techniques

Resonance technique for determining the physical properties of piezoelectric material can be difficult to implement for some low symmetry systems. Inconstancy may be introduced because several samples are needed and the degree of poling depends on sample geometry. The ultrasonic method on the other hand, allows the determination of a complete set of elastic, piezoelectric, dielectric constants ...

Characterization of piezoelectric materials with large piezoelectric and electromechanical coupling coefficients.

The relaxor based ferroelectric (1-x)Pb(Zn(1/3)Nb(2/3))O(3)-xPbTiO(3) and (1-x)Pb(Mg(1/3)Nb(2/3))O(3)-xPbTiO(3) single crystals provided new challenges in property characterization because their extraordinarily large piezoelectric coefficients and electromechanical coupling coefficients. Large errors may occur in some of the derived material constants using conventional characterization techniq...

Optimal Design of Piezoelectric Materials for Maximal Energy Harvesting

The military’s dependence on fossil fuels for electric power production in isolated settings is both logistically and monetarily expensive. Currently, the Department of Defense is actively seeking alternative methods to produce electricity, thus decreasing dependence on fossil fuels and increasing combat power. We believe piezoelectric generators have the ability to contribute to military appli...
