Gait Event Detection Using Piezoelectric Fiber Embedded Smart-Sock

We have developed a comfortable and versatile prototype smart-sock for use in gait event detection, providing additional tools for the monitoring and diagnosis of ambulance and physical activity. Through biomechanical walking trials, our smart-sock accurately and reliably detected over 95% of heel strike and toe-off gait events. Moreover, our smart-sock was subjected to over five hours of machine wash cycles without significant effect on sensing performance. We believe similar devices do not offer the same level of combined facile sensor integration and customization, washability, and measurement as our smart-sock.
