Advances in the mechanical characterization of soft materials by nanoindentation
The emergence of nanoscience has spurred the demand for technologies capable of probing physical phenomena at resolutions down to the atomic length scale. Under this initiative, recent advances in instrumented nanoindentation have made the atomic force microscope and the depth-sensing nanoindenter practical tools in studying the local material properties of a broad array of solid surfaces at mi...
متن کاملNanoindentation studies of materials
have recognized that surface contacts between materials are highly dependent on their mechanical properties1,2. Many different indentation and impression tests have been developed in an effort to measure such mechanical properties from a contact of known geometry. In the past two decades, however, a veritable revolution has occurred in indentation testing, owing to the development of new sensor...
متن کاملFlexoelectricity in soft materials and biological membranes
Flexoelectricity and the concomitant emergence of electromechanical size-effects at the nanoscale have been recently exploited to propose tantalizing concepts such as the creation of “apparently piezoelectric” materials without piezoelectric materials, e.g. graphene, emergence of “giant” piezoelectricity at the nanoscale, enhanced energy harvesting, among others. The aforementioned developments...
متن کاملAnalysis of nanoindentation of soft materials with an atomic force microscope
Nanoindentation is a popular experimental technique for characterization of the mechanical properties of soft and biological materials. With its force resolution of tens of pico-Newtons, the atomic force microscope (AFM) is well-suited for performing indentation experiments on soft materials. However, nonlinear contact and adhesion complicate such experiments. This paper critically examines the...
متن کاملSurface detection errors cause overestimation of the modulus in nanoindentation on soft materials.
The accuracy of mechanical properties from depth-sensing indentation, or nanoindentation, depends on the accuracy of the displacement measurement used to calculate these properties. Here, current nanoindentation techniques and analysis methods for accurate displacement measurements are reviewed. First, the ability of a commercial instrument to sense the surface of soft materials is examined. Se...
