Piezoelectric properties of crystals

Soviet Physics Journal, 1989
A microscopic derivation of the tensor of piezoelectric moduli is presented. The piezoelectric coefficients are expressed through the natural frequencies ωα(κ) and polarization vectorse s α (κ) associated with vibrations of the crystalline lattice.

Piezoelectric properties and microstructure of ceramicrete-based piezoelectric composites

Ceramics International, 2021
Abstract Inorganic piezoelectric ceramic composite is the potential sensing element for long-term structural health monitoring due to its excellent durability and compatibility. In this study, a Ceramicrete-based piezoelectric composite is proposed preliminarily, in which the magnesium potassium phosphate cement is used as the matrix and the lead ...

Piezoelectric properties of biological polymers

Quarterly Reviews of Biophysics, 1983
Piezoelectricity and pyroelectricity in wool and hair were observed by Martin early in 1941. The piezoelectric effect in wood was investigated in detail by Bazhenov (1961). Both converse and direct effect of shear piezoelectricity in wood was demonstrated by Fukada (1955). Bending piezoelectricity in bone was first discovered by Yasuda (1953).

Piezoelectric Properties of Dry Human Skin

IEEE Transactions on Electrical Insulation, 1986
Mechanoelectrical conversion properties of dry human skin have been examined and their origin investigated in dermis, epidermis and horny layer. Shear stress piezoelectricity is observed in all three cutaneous sections. Piezoelectric properties of dermis can be ascribed to its collagen structural network, while the piezoelectric properties of epidermis

Piezoelectric properties of SixGe1-xO2 crystals

2007 IEEE International Frequency Control Symposium Joint with the 21st European Frequency and Time Forum, 2007
We report a first measurement of several elastic, piezoelectric, and dielectric characteristics of Si0.93Ge0.07O2 crystals. This was made using the thickness modes of plates of several simple orientations, using normal and/or lateral excitation. Corrections accounting for energy trapping effect (finite electrode dimension and mass loading) or stray ...

Piezoelectric Properties of Dry and Wet Bone

Nature, 1970
FUKADA and others1–4 have demonstrated conclusively that dried bone exhibits piezoelectric properties, by direct observation of electrical potentials generated when a dried specimen of bone is stressed. The nature and source of the electrical potentials obtained from bone when it is stressed in vivo interested us, and we have investigated the general ...

Piezoelectric Properties of Ferroelectret

Ferroelectrics, 2011
Ferroelectret films (FFs) were fabricated using porous polyethylene (p-PE) film with various polarities treated by corona discharge. Their piezoelectric constant in the direction perpendicular to their surface was over 100 pC/N Hence, in order to clarify the piezoelectric motion, Piezo-Response Microscope (PRM) measurements and perpendicular elasticity
