Abstract

The Force Macroscope (FM) was presented at the MRS-Spring-2000 as a laboratory teaching tool to introduce students to concepts of Scanning Force Microscopy (SFM). It is a macroscopic version of the SFM. The FM pedagogical advantage over the SFM is its size: students relate to the FM, only a few grasp at once the concepts for the 100 [.proportional]m-long SFM cantilever. In this work we will show how we take advantage of the FMs large size to teach concepts of force reconstruction.
