> The micro robotic group at the caesar research center has recently been
awarded one of three research prizes by the ONCE foundation in Madrid. The
ONCE foundation is dedicated to the social integration of the handicapped
and blind in particular. With this EUR 60,000 prize, the Spanish
organization acknowledges the invention of a new mechanism for graphical
tactile displays for the blind by the researchers Dr. Bernhard Winzek, Dr.
Sam Schmitz and Roman Vitushinsky, thus promoting the technical
implementation of this principle.

> María Jesús San Segundo, Spanish Secretary of Education and Science, and
Carlos Rubén Fernández, President of ONCE foundation, awarded the prize to
the scientists at the historical Complutense University auditorium in
Madrid. Georg Boomgaarden, German Ambassador to Spain, also participated in
the festive award ceremony.

> The displays use metallic films featuring various shape memory alloys
which are produced layer by layer on silicon wafers using thin film
technology. Display pixels are generated when the metallic film adjusts its
curvature partially, similarly to bimetal snap plates for temperature
switches. The movement of the films is then transferred to the touch panel
via plastic pins und thus can be detected by the user. The combination of
shape memory alloys is innovative. It enables switching the film to stable
positions using different heat pulses without a permanent heat supply. Thus,
only the switching operation requires electric current, whereas maintaining
the status does not.
>
> The benefits vis-à-vis traditional Braille displays are the display's
compact structure featuring thin film technology, resulting in a cost
reduction per pixel. Using conventional Braille-cell technology, costs for
the graphic display of information emerging from the high number of pixels
required are beyond the price range of the blind. With these innovative
displays scientists make a significant contribution to the freedom in daily
life of the handicapped.

> The Bonn-based international research center caesar (center of advanced
european studies and research) commenced research in 1999. With over 220
employees, interdisciplinary teams conduct research in the areas of
biotechnology, nanotechnology and medical technology. Research and
industrial application cooperate smoothly: caesar develops innovative
products and procedures, and supports scientists in initiating new ventures.
