Marble and piezoelectricity. 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 and latent heat. Piezein which means to squeeze or. Piezoelectricity a polarization of charge produced by an applied stress occurs in many minerals. Piezoelectricity appearance of positive electric charge on one side of certain nonconducting crystals and negative charge on the opposite side when the crystals are subjected to mechanical pressure.
Piezoelectricity is a type of electricity that occurs when materials possessing piezoelectric properties are exposed to pressure or stress. This effect is exploited in a variety of practical devices such as microphones phonograph. Examples of these materials are ceramics also called piezoceramics and crystals when force is applied to such materials a voltage is generated. This is the first time a biological material has been used to make piezoelectricity.
However in may 2012 it was announced that university of california berkeley lab scientists have found a mechanism of harnessing piezoelectricity from viruses.
