Today, atomic force microscopy (AFM) is faced with the challenge of measuring 3D structures reliably. State-of-theart 3D measurements have been prone to errors since commercially available cantilevers (i.e. the measuring pins used in an AFM) do not react equally when exposed to forces from three spatial dimensions. At PTB, this problem has been successfully addressed by developing new cantilevers. These newly structured cantilevers react more sensitively to 3D influences, and they no longer tend to slip when scanning slopes that are not equally steep. (Technology Offer 476)

On the occasion of their 26th General Conference on Weights and Measures (CGPM) in November 2018 in Versailles, the signatory states of the Metre Convention decided to fundamentally reform the International System of Units (SI). This resolution stipulates that, in the future, all SI units will be based on the numerical values laid down for seven selected natural constants. In passing this resolution, the General Conference has followed a recommendation issued by the International Committee on Weights and Measures (Comité international des poids et mesures, CIPM) – the world's supreme expert committee on metrology. The new definitions of the units will come into force on 20 May 2019, World Metrology Day.
