Abstract

The present invention relates to a miniature rheometer and improved force sensor elements which may advantageously be used in combination with the miniature rheometer. The miniature rheometer is adapted to determine rheological characteristics of materials which are provided in the form of small quantity samples. The force sensor element according to the present invention allows simultaneous measurement of a shear force and a normal force applied to the sensor element. Moreover, the force sensor may employ stress-optic material.
