Patent ID: 8312779

Claim:
A force sensor for detecting a force vector applied to an elongate device, the force vector comprising a non-negligible force component along the longitudinal direction of the elongate device, wherein the force sensor comprises: a base body of monolithic construction having an end surface for receiving the force vector; one or more stress/stretching-sensitive resistors, wherein the one or more resistors are arranged on beam structures bounded by incisions, wherein the edges thereof form substantially perpendicular angles with the end surface of the base body; an energy and signal line to a measurement region of the force component F z effected over a region axially aligned with respect to the elongate device, wherein the region is narrower than the maximum width of the end surface of the base body; electrical connection surfaces attached non-perpendicularly to the axial direction of the elongate device; and a connection region including an assembly stop.
