The application of actively controlled micrometer precision positioning stages in products that are accessible to start-ups, individual consumers or third world countries is currently limited by their price and size. To solve this problem, the use of low-cost and compact components in stages is investigated. Earlier research done in the MSD...

Ferrofluid pocket bearings are a type of bearing that are able to carry a load using an air pocket encapsulated by a ferrofluid seal. Previously designed ferrofluid bearings show the great potential of the stick-slip-free and low viscous friction bearings, however until now the load capacity is limited. In this article a method is presented...

Ferrofluid pocket bearings are interesting for fast and precise positioning systems thank to the absence of stick-slip, the low viscous friction and their cost-effective nature. However, the characteristics of the bearing change due to over(de)compression since air escapes out of the enclosed pocket. This article presents an experimentally...

Ferrofluid bearings provide a cheap and passive alternative to contactless bearings such as magnetic bearings and fluid bearings. The absence of stick-slip and the low viscous friction make them interesting for high precision applications. Despite the theoretical models available in literature, the number of design rules for ferrofluid bearings...

Ferrofluid bearings have been demonstrated to be very interesting for precision positioning systems. The friction of these bearings is free of stick-slip which results in an increase of precision. More knowledge on the friction behaviour of these bearings is important for there application in precision positioning systems. This paper...

A ferrofluid pocket bearings is a type of hydrostatic bearing that uses a ferrofluid seal to encapsulate a pocket of air to carry a load. Their properties, combining a high stiffness with low (viscous) friction and absence of stick-slip, make them interesting for applications that require fast and high precision positioning. Knowledge on the...

A ferrofluid is a fluid with paramagnetic properties while having a colloidal stability. This can be used to obtain a hydrostatic type of bearing that distinguishes itself from other bearings by its compactness, inherent stability, low (viscous) friction, absence of pumps and absence of stick-slip. These properties, together with its low price,...

Precision engineering impacts every one, every day, by enabling the fabrication techniques and functions required for 21st technological revolutions. Various applications, from display technologies to sensor systems to optical networks make use of so called microelectromechanical systems (MEMS). Motions at micro level with monolithic structures...

The primary goal of this research was to study the feasibility of a thermal micro actuator for improved tracking performance of a Hard Disk Drive (HDD), and the feasibility of thermal actuation for precision micro motion and positioning in general. The fast dynamics of the micro actuator allows it to quickly correct position errors and thus...
