Additive manufacturing (AM) is a rapidly growing field that enables production of complex geometries without tooling. AM has gained traction as a method of producing complex electronic circuits not possible using traditional techniques. The method explored in this manuscript involves post-build infiltration of conductive inks into complex channels to create resistive elements with tunable properties. A Polyjet printer is used to enable high-precision multimaterial components with custom mechanical properties. Further, the conductive pathway geometry can be designed to achieve different resistive responses. These properties allow for decoupling of the stress-strain response and resistance-strain response to produce custom strain gauges with engineered properties.
