Force Platforms

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 6 Component Force Platforms-Floor Mount:

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.

Sensix makes cost effective, precise and reliable strain gauge sensor based, floor mountable 6 component Force Platforms in many sizes and Force/Torque range.

  1. Standard- 400x600 mm

  2. Large- 450x1000mm

  3. Very Large- 450x2000mm

Wearable 6 Component Force Platform solution- M3D (Wired):

The wired M3D Force Plate solution is the world's only available wearable, comercial force plate system and offers simple gait measurement by connecting the wearable , small 6 Component Force Plates at the bottom of the shoes, to a computer with a USB cable. The compact six-component force sensor can be used for a wide range of applications.

M3D Force Plate solution obviates the need for large no. of Force Plates on the ground to record GRF (Ground Recation Force) vector, and also is free from missed strike, partial strike, or double feet strike on a single force plate, as is the case with over grpund force platforms. Beng wearble, it also allows to record non-altered Gait pattern on any surface, including stairs, un-even floors and other non regular walking surfaces, as subject need not aim for the Force plates, or not be concious due to presence of visible Force Paltes.

  • Two size options are available : 80×95 (toe) / 80×80 (heel)

  • A maximum of four Plates can be used simultaneously.

  • Inertial sensors (acceleration, gyro, geomagnetic) are integrated in each Force Plate to measure simultaneously with six force components.

  • Measured data are saved as a CSV file in chronological order to allow various types of analysis.
