Abstract
The present invention relates to a parallel rheometer and improved force sensor elements, which may advantageously be used in combination with the parallel rheometer. The parallel rheometer of the present invention allows simultaneous measurements of a plurality of samples so as to allow characterization of a plurality of samples within a short time period. 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.
