Force Platforms are used for capturing ground reaction forces for Biomechanics, for Inverse dynamics Analysis. For balance studies, 3 

component platforms can work but for dynamic Gait Biomechanics analysis, 6 component Force Plates, that can capture vertical as well as shear/moments about X, Y and Z axis, are required. There are following Force Platforms available:

Sensix designs, manufactures and markets high-precision force-torque sensors and platforms through innovative dimensioning method. Sensix also offers consultancy services and solutions for the integration of its products.

Due to its six components force-torque sensors the force plate measures the force applied on its upper plate. With the location of the center of pressure, this biomechanical sensor is proving to be an indispensable tool in the evaluation of muscular effort generated by the subjects during the execution of their movement. It is very well adapted to the fields of biomechanics and medicine (sports or rehabilitation medicine) which studies are intended to analyze gestures such as walking, running or jumping. The force plate is also an essential device to measure effort which contact surface is important. Its dimensions and measuring range can be adapted to specific needs.

Description The force plate measures the 6 component effort applied on its upper face: 3 orthogonal forces and 3 moments. These measurements allow the calculation of the center of pressure position. This device uses the strain gages technology which guarantees long-term stability. The force plate consists of 

 4 3-dimensional sensors each one equipped with a signal conditioning unit 
 1 processor dedicated to the analog output calculation 

The 6 effort components are obtained by multiplying the six analog outputs by their calibration coefficients. The measuring chain must include: 

 a force plate, 
 an electronic case on which user can trigger the reset 
 a power unit 
 a DAQ card 
 a software : to display, process data and save the results. 

The DAQ Card and the software are optional. In fact, the force plates are compatible with any data acquisition system as long as they include a ±10V-analog input such as the common movement capture system. 

The force plate is available with three different measuring range 10KN (gait study), 20KN (jumping study), 40KN (high level sports study). 

Sensix offers to customize your force plate in terms of: 

 dimensions 
 measuring range 
 natural frequency 
 Additional tapped holes in order to set other devices above the force plate All these models are texture surfaced to eliminate any risk of sliding. For best accuracy, we recommend to fix the force plate to the floor. 4 mounting plate are provided. Each one is height adjustable and can be fixed to the ground using an epoxy resin.
