ADMET Inc. (Norwood, Mass.) has introduced the ADMET nmTester, a testing machine for measuring the mechanical properties of micro-sized specimens. It is equipped with a needle-type probe that is capable of indenting, scratching, pushing, pulling and bending in specific locations. It measures forces of less than 10 mN (micro-Newtons) and displacements of less than 1 mm/0.04 inch, with nanometer resolution. It is designed to work with visible light and scanning electron microscopes (SEMs) for precise positioning of the needle probe and analysis during specimen testing. It is useful for the development and testing of new materials and micro-sized devices commonly called MEMS (micro-electrical mechanical systems).
