DYNAMIC NANOINDENTER Russian patent published in 2020 - IPC G01N3/40 

FIELD: measurement technology.

SUBSTANCE: invention can be used for measuring mechanical properties of materials. Essence of invention consists in the fact that dynamic nanoindenter includes housing of device with actuator fixed on it with moving coil connected with rod, capacitive sensor and an indenter mounted on the free end of the rod is additionally provided with a power cell fixed inside the housing of the device on resilient suspensions, to the upper part of which an intermediate movable rod is attached, connected to the moving coil of the actuator and to the capacitive sensor of the actuator, movable lining of which is fixed on intermediate movable rod, for measurement of movement of housing of power cell relative to housing of device, inside the power cell housing there are flexible membranes mounted on which, on coaxial to the intermediate rod, a working rod with an indenter on the end and a capacitive force sensor are fixed, which measures the applied force based on measurements of movement of working rod 10 with respect to the housing of power cell 7. Capacitance sensor is placed under the lower resilient suspension to measure the displacement of the working rod relative to the body of the instrument and to determine the immersion depth of the indenter into the test material, the cover plate and the capacitive force sensor and the displacement displacement capacitive sensor are fixed on the movable working rod.

EFFECT: enabling expansion of functional capabilities of a dynamic nanoindenter.
