Piezoelectric Resonance Analysis Program (PRAP)
PRAP analyses piezoelectric resonance spectra to determine effective elastic, dielectric, piezoelectric, and electromechanical coupling constants. These constants are complex and so include account for losses. The software can also directly acquire resonance spectra from a variety of instrumentation.

Additional Product Information
PRAP (the Piezoelectric Resonance Analysis Program) analyses piezoelectric resonance spectra to determine effective elastic, dielectric, piezoelectric, and electromechanical coupling constants for the resonator. These constants are complex and so include account for losses. Typical resonators are anisotropic and are composed of PVDF, PZT, or composite materials. , Resonance spectra are collected by measuring the complex impedance of a sample as a function of frequency using an impedance analyser, LCR meter, or network analyser. The spectra are then modelled using modified forms of the analytical equations given in the IEEE standard on Piezoelectricity or using circuit models for the resonator at the fundamental resonance (Van Dyke's circuit model, or a complex circuit model). , The PRAP Basic Package imports resonance spectra and analyses seven common 6mm (C-infinity) resonance modes; length, thickness, length-thickness, a rotated thickness, and radial extensional, and the length and thickness shear modes. Optional additional analysis modules support other sample geometries such as a backed or thin film resonator, stack resonator, the bimorph resonator, etc. Other optional analysis modules support analysis of crystal symmetries other than 6mm, such as the 4mm (C4v) crystal symmetry. The optional basic data acquisition module includes an ISA GPIB card to interface directly with the impedance analyser. At the moment, the HP4192a and HP4194a, HP4195a, and Solartron 1260 analysers are supported, but others will be added on demand. Also included with the basic data acquisition module are drivers for a variety of temperature controllers, DC power supplies (for DC bias measurements such as with electrostrictives), and stress instruments. Optional data acquisition modules extend the basic data acquisition module to perform resonance spectra measurements as a function of DC bias, temperature, time, etc., The PRAP Version 2.11 Basic Package includes the compound file where resonance spectra can be analysed collectively. This allows for completing statistical studies of your measurements and a utility for constructing the complete piezoelectric matrix of C-infinity materials. Additional optional analysis modules for the basic modes of other crystal symmetries include tools for constructing the complete piezoelectric matrix of those materials. Using the compound file, material properties can also be studied as a function of a measurement parameter such as temperature, DC bias, etc.
