Abstract
The invention relates to an apparatus and a method for measuring mechanical properties of materials using an indenter which has a predetermined geometry, a device for generating force permitting the indenter to penetrate into a material sample surface of an object of measurement, and a device for measuring the penetration depth, wherein, arranged between a force application portion on which the device for generating force is applied and a shaft with an indenter tip facing towards the material surface of the object of measurement, the indenter has at least one micro-mechanical motion actuator by which at least one radial deflection of the shaft with respect to the force absorption portion of the indenter is capable of being activated or detected.
