DEVICE FOR DETERMINING PRESSURE IN THE PROCESS OF WRITING Russian patent published in 2023 - IPC G01L1/22 B43K29/20 

FIELD: medical engineering.

SUBSTANCE: method for measuring the force characteristics of pressing a pen in the process of writing a text. The standard pen containing the paste cartridge is a pressure measuring device. To do this, the free end of the cartridge was used as a power input unit, which transmits the pressing force to a bracket fixed in the body of a fountain pen, on the beam of which a bridge with the topology of semiconductor strain gauges was fixed, equipped with an insulating substrate in the form of a dumbbell. The width ratio of the narrow and wide parts of the dumbbell is chosen so that the deformation of the beam through the adhesive layer is accurately transmitted to the strain gauges.

EFFECT: providing the possibility of quantifying the amount of pressure using a device based on a ballpoint pen.
