What is a 3D force plate?
A 3D force plate is a measuring platform that is used in rehabilitation, for example, for gait and balance analysis or in sport for measuring highly dynamic movement sequences. The force to be measured is applied via a cover plate to four 3-component force sensors, which are installed under high pretension between a mounting foot and the cover plate.
Each of the sensors is equipped with three quartz plate pairs, of which one responds to pressure in the z-direction and the two others shear in the x and y directions. Measurement takes place practically displacement free.
