Smart Shoe

Smart shoe
XOnano Smartshoe can measure 3D GRF outside the lab. Capture human performance during the heat of competition.

Our Smart Shoe, powered by XOnano Smartfoam, will replace instrumented treadmills and force plates. We insert four Smartfoam sensors in the heel, arch, ball and toe of the foot and can transform any shoe into a smart shoe. Our smart shoe can measure 3D GRF at an accuracy rate of 97% of force plates and treadmills. Read more about our performance here.

With our smart shoe, you can conduct gait analysis outside of the lab. Labs perform a vital function, but they do not account for the emotion associated with competition. With our shoe, we can study human performance during live competition and in all weather conditions. We can provide data where athletes train and perform, unlike instrumented treadmills and force plates.

The gold-standard of GRD: expensive, immobile instrumented treadmills.

Gait analysis is an essential tool in identifying and understanding human movement. The modeling of three-dimensional ground reaction forces (3D GRF) is an important element of gait analysis. GRF analysis can be used to identify key gait parameters such as cadence, heel strike, and toe off. The measurement of GRF now requires a subject to walk across a force plate, which is affixed in a floor or to a treadmill. These devices are expensive and can only be used in laboratory environments. Further, only a few steps can be recorded at a time making data collection time-intensive and inefficient.

Treadmills instrumented with force platforms can be used to collect more data; however, these treadmills cost approximately ten times more than a traditional force platform. Such a cost prohibits many researchers from obtaining treadmill GRF data. These issues have led to a technological push in the development of mobile force sensors, which could open new possibilities for applied gait analysis.
