Objectifs du cours
One of the main engineering challenges in micro- and nano-technologies is the precision positioning by the production, manipulation and assembly of microcomponents. ln this frame the adoption of positioning systems based on compliant mechanisms allows several advantages to be obtained, thus simplifying the design and reducing the costs.
In this course the basic design principles of mechanisms based on elastic elements will be presented. The limits of applicability of the approaches used to model the behaviour of such mechanisms will be established and verified with experimental data. Several examples of the practical usage of compliant mechanisms will be given.
Public cible
The course addresses a wide range of engineers and scientists from microtechnologies, manufacturing, metrology, optics, astrophysics and other industry and research organizations, i.e. anyone facing the challenges of high-precision positioning.

Enseignant(s)
Dr. S. Zelenika, Head of the Division of Mechanical Engineering Sciences at Paul Scherrer Institut and Assistant Professor in Machine Design at the University of Rijeka, Croatia.
S. Zelenika studied Mechanical Engineering and obtained a PhD for his work on high-precision positioning systems. From 1991 to 1996 he has worked on precision positioning problems at the Sincrotrone Trieste, under the leadership of the Nobel laureate C. Rubbia. After a career in industry (1996-1998), he joined the Paul Scherrer Institut in 1998, dealing again with precision positioning topics.
He has authored more than 35 scientific papers on precision positioning published in the most renown international scientific journals or presented at international and national conferences, as well as several patents, internal scientific papers and design studies.
