Queensgate offers a range of diverse Piezo-driven actuators that are at the forefront of nanopositioning applications in material science, semiconductor manufacturing, astronomy, and life sciences – but did you know that the technology is based on a discovery that was made in the 19th Century?
The piezoelectric effect was discovered in 1890 by Pierre and Jacques Curie. By applying a mechanical force to certain materials such as quartz crystals, they found out that the quartz crystal generated an electric current. In 1891 they demonstrated the inverse piezoelectric effect: where they applied an electrical field to a quartz crystal causing it to physically deform, leading to minute changes in its physical structure.
The inverse piezoelectric effect is used in our Queensgate nano actuation systems – a highly refined and controlled form, allowing for highly precise movements measured in nanometres, with picometer accuracy.
