The concept of measuring or moving with sub-nanometric accuracy was once considered unattainable. Today, Queensgate Instruments advanced NanoSensor and NanoPositioning technology has turned this concept into reality.
The ability to move or measure with sub-nanometre precision is essential in the production of some of the most advanced products in use today.
Piezo electric devices have the potential to meet the resolution requirements. However, because piezo electric devices are non-linear and exhibit hysteresis, a sensor must be used to monitor and control their position. The Capacitance sensor is ideally suited to this task, being small and with sub-atomic resolution capability. To design a NanoMechanism involves combining the piezoelectric actuator and capacitance position sensor with flexure hinges and mechanical amplifiers in such a way to produce a device capable of making pure orthogonal motions with sub nanometre precision.
