Electronic devices can be printed on the surface of a workpiece by screen printing. A special strain gauge coating used to measure the elongation of sheet metal parts by a change in the electrical resistance is developed at PtU in the recent years. Printed strain gauges have a high potential regarding their cost efficiency and are less sensible to damage. Furthermore, they can be applied on a workpiece prior to a forming process. Due to this fact, they can be used for inline measurements during the manufacturing operation, too. The design of the printing pattern can easily be adjusted to create strain gauges with an adopted geometry.Challenges regarding the usability of printed strain gauges are considerable fluctuations of the screen printing process, which are leading to irregularities of the initial resistance.This paper focuses on the homogenization of printed strain gauges with the objective to wire up four equalized strain gauges on one sheet metal specimen to a Wheatstone bridge for precise strain measurements.The homogenization is achieved by two different approaches within the scope of this paper. First, machine hammer peening technology is used to mechanically adjust the surface layer properties and change the initial resistance. The second method for a homogenization is a laser heat treatment.It is shown, that a homogenization of printed strain gauges is feasible using the methods presented.
