Abstract:
A force sensor for measuring a force applied thereto comprising:an elastically deformable carrier elongated in a first direction; said deformable carrier being adapted to be supported by a supporting surface with said first direction parallel to the supporting surface; said deformable carrier being deformable in response to a force applied to said sensor; first and second strain measuring elements associated with said carrier; one of said first and second strain measuring elements being compressed in response to a force applied to said elongated carrier in a direction perpendicular to said first direction of elongation and perpendicular to the supporting surface; the other of said first and second strain measuring elements being extended in response to a force applied to said elongated carrier in a direction perpendicular to said first direction of elongation and perpendicular to the supporting surface; whereby said sensor provides an indication of the magnitude of a force applied to said elongated carrier in a direction perpendicular to said first direction of elongation and perpendicular to the supporting surface based upon changes in said first and second strain measuring elements.
