More on Dr. Sanders at University of Washington:
Kate Allyn, CPO, is the prosthetist on the project, which is being
led by Sanders at her lab at the University of Washington Department
of Bioengineering.
"[The small changes] have a big impact because they maintain a fit
between residual limb and socket that is not too tight and not too
loose-but just right," said Allyn.
A gel interface material in the prosthetic sleeve contains a small
amount of iron, and sensors embedded in the socket wall detect the
distance to the iron in the gel and send that data to the socket´s
microcontroller. The microcontroller calculates whether adjustments
are needed. If so, it transmits instructions to three motorized
panels within the socket wall-two in the front, one in the back-and
they move to make the socket smaller or larger in increments less
than a millimeter at a time. Changes can also be controlled manually
via an app on the user´s smartphone.
