University of Washington researcher creates sensor‑embedded prosthetic sockets

Prof. Joan Sanders of the University of Washington has led a research team that devised a rapid, efficient technique for fabricating lower‑limb prosthetic sockets embedded with real‑time fit‑monitoring sensors. The findings, published as the lead author in the journal Frontiers in Rehabilitation Sciences, describe how the new method integrates miniature pressure sensors directly into the socket material, allowing continuous measurement of how the socket’s interface with the residual limb changes during everyday activities.

The embedded sensors transmit data that can alert prosthetists to shifts in pressure distribution, indicating when a socket becomes too tight, loose, or unevenly loaded. By providing immediate feedback, the technology promises to streamline adjustments, reduce the need for multiple clinic visits, and improve comfort for amputees. Sanders suggests that, with further development, the system could become a standard tool for personalized prosthetic care, enabling clinicians to adapt sockets proactively as patients’ needs evolve.
