Potassium sodium tartrate tetrahydrate, commonly known as Rochelle salt, is a double salt of tartaric acid. It was among the first materials discovered to exhibit piezoelectricity, leading to its historical use in electronic components such as crystal phonograph cartridges, microphones, and earpieces.
