It all began in France more than 120 years ago. The two Curie brothers Jacques and Pierre discovered that by compressing a crystalline material such as Rochelle salt they could create electric voltage. The interesting thing is that the opposite is also true – if you place an electric field over a piezo crystal it changes shape. It is this shape-changing capacity that is the basis for PiezoMotor’s micro motor technology. Instead of Rochelle salt, piezoceramic materials have been developed to meet the requirements of modern applications.
Piezoelectric motors have been around for many decades. The first motors were developed fairly simultaneously by researchers in the former Soviet Union and in the USA. However, it was not until the 1980s that the motors appeared in high numbers in commercial products.
