Piezoelectricity is also used, much more crudely, in spark lighters for gas stoves and barbecues. Press a lighter switch and you'll hear a clicking sound and see sparks appear. What you're doing, when you press the switch, is squeezing a piezoelectric crystal, generating a voltage, and making a spark fly across a small gap.

The major contributions of Pierre Curie are discovery of piezoelectricity,invention of the piezoelectric quartz, formulation of the principle of symmetry, invention of the Curie …

Quartz is for the most part, largely the same stuff, but in a larger unbroken crystal. Grinding or machining it should only be done with a proper respirator. And heaven help you if it makes it's way into the sliding surfaces of a machine tool.That would be like putting fine sandpaper in those joints.

The phenomenon of piezoelectricity was discovered by brothers Curie: Pierre (1859–1906) and Jacques (1855–1941). In 1880 they found (Curie and Curie 1880) that some crystals when compressed in certain directions show positive and negative charges on some portions of the surface.These charges are proportional to the pressure and …
