This type of microphone uses piezoelectric materials to transform vibrations into electrical signals. Early mics used Rochelle salt due to its impressive output, but it was somewhat fragile and sensitive to moisture. Later devices used ceramic materials such as lead zirconate and barium titanate. They...
