Abstract
A multi-junction resistance strain gauge comprises a substrate; a sinterable ink deposited directly on the substrate forming a non-conductive pattern; a stripe pattern generated on the sinterable ink by sintering, the stripe pattern having one or more non-conductive gaps, the stripe pattern having a first electrical conductivity; a sintered bridge across each of the one or more gaps and providing electrical continuity through the stripe and across the gaps, each bridge having a second electrical conductivity which is lower than the first electrical conductivity. The substrate is a non-conductive material or a conductive material coated with a thin insulator on which the stripe pattern is generated. The sinterable ink is a silver ink. The first electrical conductivity and the second electrical conductivity comprise different electrical conductivity. The first electrical conductivity of the stripe is a factor of about 1.7 or more higher than the second electrical conductivity of the bridge.
