Piezo Controller Thermal Stability Comparison

Piezo controller design can have a significant effect on thermal stability, causing excessive error in precision motion applications. In this technical note, we briefly describe some techniques used for controlling thermal effects and compare the thermal stability of Aerotech’s piezo control electronics with a competitive design. Thermal stability is paramount in any precision process. Thermal…

Piezo Engineering Tutorial

The Direct and Inverse Piezoelectric Effect In 1880, while performing experiments with tourmaline, quartz, topaz, cane sugar and Rochelle salt crystals, Pierre and Jacques Curie discovered that when mechanical stress was applied to a crystal, faint electric charges developed on the surface of that crystal. The prefix “piezo” comes from the Greek piezein, which means…
