Most prosthetic sockets have traditionally been made from a cast or scan of the residual limb. That can capture shape really well, but not the pressure points and force patterns that show up in real life.
This research took a different approach. Instead of stopping at shape, the team used a pressure-sensing liner to track how the limb handled load during activities like walking, standing, and shifting weight. That data was then fed into AI software, which helped create a 3D-printed socket designed around real movement.
