Abstract

The nanonewton force facility of Physikalisch-Technische Bundesanstalt (PTB), Germany, has been significantly improved. We demonstrate the possibility of using the facility as a calibration device that can accurately determine spring constants of soft cantilevers (k <; 0.1 N · m-1) with traceability to the SI units. This paper is described the possibility of increasing the range of the measured fo...
