... in piezo lighters?

1 Answer

Answer :

The piezoelectric effect can only occur with crystals that do not have a center of symmetry. The best known piezoelectric substance is monocrystalline quartz, crystal or barium thianate. For the first time, a piezoelectric effect was observed with the Seignett salt (potassium sodium tartrate tetrahydrate).
