In 1880, brothers and colleagues Jacques and Pierre Curie discovered that putting pressure on certain materials created electricity. Taken from the Greek word for “squeeze” (piezein), piezoelectricity was born. Commonly known as the “piezo effect,” it also occurs when an electrical field is applied and changes the dimensions of materials. More than 100 years later, PI Ceramic (a division of PI Physik Instrumente) is a leader in the field of piezo ceramic components, including its newest line of mini transducers.
