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 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 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

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 ...

Piezoelectricity as a Fundamental Property of Biological Tissues

Nature, 1967
Piezoelectric effects have been produced in a number of soft tissues, as well as hard, and appear to be associated with the presence of oriented fibrous proteins such as collagen. Thus, piezoelectricity may be a universal property of living tissue, and may play a significant part in several physiological ...

Piezoelectric and mechanical properties in bovine cornea

Journal of Biomedical Materials Research Part A, 2003
AbstractThe piezoelectric coefficient (d31) and Young's modulus (E) were investigated as a function of degree of hydration for bovine cornea. The piezoelectric and mechanical responses observed were anisotropic, and d31 decreased, whereas E increased with decreasing the degree of hydration.

Electric properties of an embedded piezoelectric layer

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 1994
The one-dimensional vibration mode of a piezoelectric layer under different load conditions has been reconsidered. Derived analytical expressions for admittance and impedance at special frequencies are listed. Based on the expressions derived, two applications are proposed involving electrical measurements on a piezoelectric plate.
