What is piezo ceramic?
In 1880, the French physicists brothers of Jacques & Pierre Curie discovered that pressure generates electrical charges in a number of ceramics and crystals; they called this phenomenon the „piezoelectric effect”. Later they noticed that electrical fields can deform piezoelectric materials. This effect is called the „inverse piezoelectric effect”. Piezo Ceramics is the material in which one can take advantage of the piezoelectric effect.
