A new bending stage is proposed to test materials at micro/nano scale. The stage minimizes uniaxial tension but maximizes pure bending stress to avoid premature fracture. The stage consists of force and displacement sensors, as well as the material sample – all of which are cofabricated. Thus the problem of specimen handling and alignment are avoided. The stage allows both quantitative and in-situ tests in SEM and TEM chambers. Here, an analytical and a numerical model of the stage are presented. The model predicts the deformation and stresses in the specimen upon loading. In order to test the feasibility of the proposed design, a 3D printed stage and a sample are fabricated using Polyamide PA2200. Bending tests are then carried out. Elastic modulus of the sample is measured which matches with the modulus reported in the literature.
