The word ‘piezo’ is derived from the Greek word for pressure. The piezoelectric effect was discovered by Jacques and Pierre Curie in 1880. They found that pressure applied to a quartz crystal creates an electric charge in the crystal, a phenomenon they referred to as the (direct) piezoelectric effect. Later they also verified that an electric field applied to the crystal leads to a deformation of the material: the inverse piezoelectric effect. In the subsequent century, research has been performed into the development of materials with improved piezoelectric properties, enabling commercial utilization of the piezoelectric phenomenon. To date, the number of applications of piezoelectric materials is still increasing...
