Abstract

The invention presents a method and a correspondingly designed probe for achieving uniform stress distribution when experiencing deflection. The probe has a top edge, a bottom edge, a tip, and a beam portion defined by selecting an inflection point along the top edge, such that the beam portion is contained between the tip and the inflection point, and the bottom edge below the beam portion is approximately straight, while the curvature of the top edge of the beam portion is fitted to a parabola. The tip has an outer edge, an inner edge, and a point of contact at the location where the outer and inner edges join. The inner edge is approximately straight while the curvature of the outer edge is fitted to a second parabola. The probe is preferably mounted in a support structure having a groove for receiving the probe such that the beam portion is free to move vertically in the groove and constrained laterally to prevent side-buckling.
