Abstract: A weldable strain sensor assembly configured to be joined to an instrumented component includes: a stand-off; a substrate disposed on top of the stand-off; and a sensing component disposed on a top or a bottom of the substrate; wherein the combination of the stand-off and the substrate are configured to suspend the sensing component over the instrumented component with a defined gap between the instrumented component and at least one of: the substrate; and, the sensing component.

Abstract: A force sensor includes: a substrate that forms a three-dimensional, 3D, body disposed about a central z-axis of an r, ?, z-cylindrical coordinate system, the 3D body having a first surface, an second surface, and a sidewall disposed between the first and second surfaces, wherein the sidewall at least partially encloses a void in the 3D body that extends from and through the first surface to and through the second surface; an electrical circuit disposed on either one of the first surface or the second surface, the electrical circuit having at least one strain gauge, and a plurality of electrical terminals electrically connected to the at least one strain gauge; wherein the sidewall includes at least one strain focusing feature; wherein the at least one strain gauge is disposed proximate to the at least one strain focusing feature.

Abstract: An instrumented pin sensor includes: a support body in the form of a pin having an axial cross section that is only partially circular, forming a first outer surface with a profile that follows the partially circular axial cross section, and a second outer surface with a profile that does not follow the partially circular axial cross section; a strain sensing electrical circuit having at least one strain sensing gauge, the strain sensing electrical circuit fixedly disposed on the second outer surface; a plurality of electrical leads having a first end electrically connected to the strain sensing electrical circuit and fixedly attached to the second outer surface of the support body, and a second end extending from the support body; wherein the second outer surface runs the entire length of the support body with material of the support body only on an underside of the second outer surface.
