Abstract

Various deficiencies in the prior art are addressed by systems, methods, architectures, mechanisms and/or apparatus configured for fabricating a strain sensing device directly on a structure by printing a material on the structure, the material exhibiting a piezo-resistive effect, and sintering a strain sensing pattern from the material such that the strain sensing pattern becomes electrically conductive.
