This paper describes the preliminary results of the design, development and characterization of precision artifacts for the measurement of low forces of 1 N and 2 N. For designing the elastic element, we carried out the finite element analysis (FE) to determine the stress and strain distribution on the elastic element for appropriately identifying the location for fixing the strain gauges. In order to obtain optimum performance and sensitivity, the strain gauges are emplaced on the identified location using a high quality curing adhesive. Characterization of these artifacts are performed on a recently developed low force dead weight machine having an estimated best measurement capability (BMC) of +/- 0.0012% (k=2). The repeatability and reproducibility of the developed artifact are found to be within +/- 0.003% and +/- 0.006% respectively
