FORCE SENSING SHOE SOLE
Club Project

OBJECTIVE

Reduce injuries caused by improper running form by creating a shoe insert that monitors foot impact. Evaluate foot impact to assist the runner in making improvements.

DETAILS

  • Three force sensing resistors connected to an Arduino Nano

  • Sensors enclosed in sealed waterproof fabric and placed under shoe sole

  • Arduino Nano housing clipped to shoelace

  • Impact data collected for the forefoot, midfoot, and heel stored on micro-SD card

  • Rechargeable battery pack within housing 

  • Beginnings of Android UI app built

  • Logged data allows tracking of progress
