Summary

  • Customer Need / Challenge

    Customer would like to know how a prosthetic foot responds as it is loaded during different stances.

  • Interface Solution

    Interface’s 3A120 3-Axis Load Cell was installed between the leg socket and the prosthetic foot. The 3A120 was then connected to the BX3-HD44-CAN 3-Channel CANbus AND USB Strain Gage Amplifier to determine and collect data points.

  • Results

    Data was logged for X, Y, and Z axis. Customer was able to review the results and identify premature foot flat and dead spots during foot’s use. They can now make improvements to the design.

Materials


  • 3A120 3-Axis Load Cell
  • BX3-HD44-CAN 3-Channel CANbus AND USB Strain Gage Amplifier
  • Prosthetic foot undergoing test

How it Works


  1. Install the 3A120 into prosthetic foot load stream. The BX3-HD44-CAN 3-Channel CANbus AND USB Strain Gage Amplifier collects the force readings where it can be displayed and monitored when conneced to the customer’s computer with supplied BlueDAQ sofware.
  2. Review X, Y and Z force measurements to determine foot flat and dead spots with customer instrumentation.
