| Over
the last two decades we have observed astonishing progress
in nanotechnology. This progress is partially due to the
invention of Atomic Force Microscope (AFM) in the 1980s,
which has made a significant impact on numerous fields.
A conventional atomic force microscope is rather slow,
taking up to a minute or longer to develop an image. A
high-speed atomic force microscope is needed to acquire
high resolution, three-dimensional, time-lapse images
of fast processes such as the rapid movement of cells
and the diffusion of DNA molecules. In this talk we concentrate
on mechanical design of high-speed scanners, the fundamental
role of feedback, and the need for model-based control
design methods in increasing accuracy and speed of operation
of atomic force microscopes. We also will explain how
similar ideas have led to the highest reported data storage
density in a MEMS-based data storage device, in which
an array of thousands of AFM-type levers are used to store
digital information as tiny indentation on a polymer storage
medium. |

Dr.
Reza Moheimani joined The University of Newcastle, Australia
in 1997, where he founded and directs the Laboratory
for Dynamics and Control of Nanosystems, a multi-million-dollar
state-of-the-art research facility dedicated to the
advancement of nanotechnology through innovations in
systems and control engineering. He is a Professor of
Electrical Engineering and an Australian Research Council
(ARC) Future Fellow. His current research interests
are mainly in the area of dynamics and control at the
nanometer scale, and include applications of control
and estimation in nanopositioning systems for high-speed
scanning probe microscopy, modeling and control of micro-cantilever
based devices, control of electrostatic microactuators
in microelectromechanical systems (MEMS) and control
issues related to ultrahigh-density probe-based data
storage systems.
Dr. Reza is a Fellow of IEEE,
a Fellow of IFAC and a Fellow of the Institute of Physics
(UK). He is a co-recipient of the 2007 IEEE Transactions
on Control Systems Technology Outstanding Paper Award,
and the 2009 IEEE Control Systems Technology Award,
together with a group of researchers from IBM Zurich
Research Labs, where he has held several visiting appointments.
He has served on the editorial board of a number of
journals including the IEEE Transactions on Control
Systems Technology, the IEEE/ASME Transactions on Mechatronics
and Control Engineering Practice, and has chaired several
international conferences and workshops.
