The Importance of Cryogenic Nanopositioning in Scientific Research
Precise positioning of objects in nanometer increments is a critical requirement in the development of quantum systems for scientific research, particularly in fields such as materials science and biotechnology. Nanopositioners play a vital role in achieving this level of precision by enabling accurate movement and positioning (link).
However, working with nanopositioners in cryogenic environments presents unique challenges. The extreme cold temperatures, often below 4 Kelvin (-269°C), pose difficulties for conventional nanopositioners due to issues like excessive heat dissipation, high vibration levels, and drift. To overcome these challenges, significant advancements have been made in cryogenic nanopositioning technology, leading to the emergence of a new generation of nanopositioners capable of operating reliably at these extremely low temperatures.
In this article, we will explore the revolutionary technology called “Cryo-Walking” and its significant impact on the development of arQtika, a cutting-edge class of nanopositioners specifically designed for low-temperature applications, by Onnes Technologies.
The Advantages of Cryo-Walking
Conventional nanopositioning systems typically employ stick-slip motion, which heavily relies on the difference between static and dynamic friction. Unfortunately, this mechanism generates substantial amounts of heat and vibration. The dissipated heat can lead to temperature instability around the nanopositioner, posing challenges for consistent and reliable experimental conditions. Additionally, the vibrations caused by traditional nanopositioners can induce drift, making object positioning with high precision impossible.
However, Cryo-Walking, a groundbreaking technology, has revolutionized the field. Unlike its conventional counterparts, Cryo-Walking operates on a different actuation mechanism that produces ultra low heat and virtually no vibration, even in cryogenic environments. At the core of Cryo-Walking is a unique mechanical design in combination of piezoelectric elements operating in static regime.
By utilizing a piezoelectric actuator, Cryo-Walking effectively "walks" objects along a surface, employing opposing forces to securely hold the object in place. This innovative approach results in a highly stable nanopositioning system, even when operating at extremely low temperatures.
