... this wire was bent and electrochemically etched to serve as a probing tip. With a typical length of 12 mm and diameters of 0.25 and 0.5 mm, they obtained force constants of 150 and 2500 N/m, respectively, ... controlled directly but had to be estimated. Second, the cantilevers used had a high force constant. The rapid development of SFM led, on the one hand, to microfabricated...
