Barium titanate, lead titanate, and lead zirconate are all piezoelectric materials. Cadmium sulfate is not a piezoelectric material.<\/p>\n<p>Barium titanate is a ceramic material that is used in a variety of applications, including piezoelectric sensors, actuators, and filters. It is a ferroelectric material, which means that it has a permanent electric polarization. When an electric field is applied to barium titanate, the polarization changes, which causes the material to change shape. This property is used in piezoelectric sensors to detect mechanical stress or vibration.
