Difference between piezoelectric and triboelectric
Answers
The piezoelectric charge is permanent and it will measure the same every time. The triboelectric charge is temporary and may not be there the next time you measure the charge. Charge generation from a piezoelectric material if through deformation, while charge generation from triboelectric means is rubbing or adhesion.Triboelectricity is not related to piezoelectricity other than the fact that piezoelectricity involves permanent electrostatic charge and triboelectricity involves temporary electrostatic charge. Triboelectricity is simply the generation of a static electrical charge by friction. The triboelectric effect describes frictional charge generation that happens when certain materials become electrically charged after being separated from a second material to which they were in contact. Rubbing the two materials together increases the contact between their surfaces, and creates the triboelectric charge. Rubbing glass with fur or a plastic comb through the hair, can build up a triboelectric charge. Basically triboelectric charge generation is everyday static electricity. The polarity and strength of the charge produced depend upon the materials, surface roughness, temperature, and other properties.
