Piezoelectricity
Piezoelectricity, is electricity resulting from pressure and heat that accumulates in solid materials, most particularly crystals, which are a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure that form a lattice structure that extends in all directions.
Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure. It is derived from the Greek piezo or piezein, which means to squeeze or press, and electric or electron, which means amber, an ancient source of electric charge.[1]
Piezoelectricity is found in useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, to drive an ultrasonic nozzle, and ultrafine focusing of optical assemblies.
The first practical application for piezoelectric devices was sonar, first developed during World War I. The detector consisted of a transducer, made of thin quartz crystals carefully glued between two steel plates, and a hydrophone to detect the returned echo. By emitting a high-frequency pulse from the transducer, and measuring the amount of time it takes to hear an echo from the sound waves bouncing off an object, one can calculate the distance to that object. The use of piezoelectricity in sonar, and the success of that project, created intense development interest in piezoelectric devices.
Materials
Many materials, both natural and synthetic, exhibit piezoelectricity:
- Naturally occurring crystals
- Quartz
- Berlinite (AlPO4), a rare phosphate mineral that is structurally identical to quartz
- Sucrose (table sugar)
- Rochelle salt
- Topaz
- Tourmaline-group minerals
- Lead titanate (PbTiO3).
The action of piezoelectricity in Topaz can probably be attributed to ordering of the (F,OH) in its lattice, which is otherwise centrosymmetric: Orthorhombic Bipyramidal (mmm). Topaz has anomalous optical properties which are attributed to such ordering.
Bone
Dry bone exhibits some piezoelectric properties. Studies of Fukada et al. showed that these are not due to the apatite crystals, which are centrosymmetric, thus non-piezoelectric, but due to collagen. Collagen exhibits the polar uniaxial orientation of molecular dipoles in its structure and can be considered as bioelectret, a sort of dielectric material exhibiting quasipermanent space charge and dipolar charge. Potentials are thought to occur when a number of collagen molecules are stressed in the same way displacing significant numbers of the charge carriers from the inside to the surface of the specimen. Piezoelectricity of single individual collagen fibrils was measured using piezoresponse force microscopy, and it was shown that collagen fibrils behave predominantly as shear piezoelectric materials.
Other natural materials
Biological materials exhibiting piezoelectric properties include:
- Tendon
- Silk
- Wood due to piezoelectric texture
- Enamel
- Dentin
- DNA
- Viral proteins, including those from bacteriophage. One study has found that thin films of M13 bacteriophage can be used to construct a piezoelectric generator sufficient to operate a liquid crystal display.
Alien Machinery
Essentially the alien's technological manipulation of the Black Subtle Forces and dark matter have been used to manipulate and suppress the molecular structure in matter, producing artificial magnetic effects in order to compact and compress the molecular structure of the earth body and the human body. Molecular compression is similarly to the piezo-electric effect, as matter is being squeezed it gives off biological light emissions. In order to comprehend the nature of primal subtle forces, and the reasons behind the NAA proliferating more and more of the black subtle forces in the earth, we will discuss these primal forces more deeply.[2]
