In this study a novel micromechanical device has been developed. Precision of the setup has been evaluated using specimens of known material properties. Applied force was measured with capacity load sensor and the strains were measured optically. Samples of trabeculae were harvested from human proximal femur. A FE model of trabecula was developed and three-point bending test was simulated. From displacements of markers, strain values were computed. Resulting displacements of markers from FEA were fitted to experimentally obtained ones and set of parameters of the material model was determined.
