N2 - Strain gages developed using high-definition direct write technology enable direct bonding to substrates without an adhesive layer, so greater shear forces may be faithfully transmitted and thicker, more robust conductors may be used for strain-sensing. Effects of hysteresis, creep, and temperature limitations common to adhesively-bonded gages can also be mitigated. Manufacture and installation of the gage (and lead wires) are automatic and simultaneous, reducing preparation time and cost. Using the above developed method, industrial-grade strain gages have been fabricated and tested. Standard gage resistances between 120Ω-350Ω have been achieved on grids smaller than 10mm2 using nickel-chrome as the gage material. Thermal plasma-sprayed laser-cut resistive gages have achieved gage factors of 1.3, operating linearly and repeatably for more than 105 cycles between ±1000με. Additional performance metrics e.g., temperature sensitivity and compensation, will be treated in this paper.
