Abstract: Indentation techniques based on atomic force microscopy (AFM) have been widely used in characterizing the mechanical properties of various types of materials, due to their high lateral resolution and vertical precision. This review article begins with a concise introduction to the fundamental principles of AFM and related indentation techniques. Subsequently, it extensively discusses and reviews the applications of AFM-based indentation techniques in measuring the mechanical properties of low-dimensional materials, biological materials, etc. This article also reviews the latest progress of the applications of AFM in the research of high-pressure phase transition in two-dimensional materials. Particularly, we introduce a novel angstrom-indentation technique, which enables atomic-level deformation on the samples. Angstrom-indentation allows for highly effective characterization and tuning of the interlayer coupling in two-dimensional materials. Finally, we make an outlook on the development of AFM-based indentation techniques.
