Stevens Institute of Technology researchers have developed a smart insole powered by artificial intelligence (AI) that analyzes a person's gait in real time when worn in their shoe.
Stevens Wearable Robotic Systems Laboratory director Damiano Zanotto and colleagues designed the SportSole to monitor its movement and spatial orientation with accelerometers and gyroscopes, while force sensors detect plantar pressure.
The SportSole makes 500 readings each second, which Zanotto condenses to a few key features that are fed to an AI algorithm that extracts gait parameters accurate to within a few percentage points.
The SportSole operates whether the wearer is walking or running, and does not require customization for individual users.
Zanotto said, "We're achieving the same or better results [as high-end sensors] at a far lower cost, and that's a big deal when it comes to scaling this technology."
