Title:
SURFACE COMPRISING AN ARRANGEMENT OF A PLURALITY OF COLUMN-SHAPED ELEVATIONS, AND USES THEREOF
Document Type and Number:
WIPO Patent Application WO2005049479
Kind Code:
A3
Abstract:
The invention relates to objects comprising at least one microstructured surface area with an arrangement of a plurality of column-shaped elevations that have a length L and a cross-sectional area A and are made of an elastically deformable material. At least 90 percent of the column-shaped elevations have a length (L90 value) of at least 5 ñm while relation (I) applies to at least 90 percent of the column-shaped elevations. The invention particularly relates to objects that are embodied as sensors for determining forces and a measurement system encompassing such a sensor.
