Users have always had high expectations for the
function of artificial upper limbs, often because of
their portrayal in the popular media and comparisons
with nondisabled people. Only a small percentage
of patients with an upper-limb amputation regularly
use a prosthesis, mainly because many patients perceive
a lack of function. Externally powered prostheses
can be controlled by muscle signals from the
residual limb, but they can still be difficult for users
to control. In this study, we investigated the use of
novel high-density force sensors that measure pressure
from muscle movements as a possible control
input for an upper-limb prosthesis, with the goal of
developing a more robust prosthetic control method.
Our high-density force sensor method showed greater
accuracy in recognizing movements of the wrist
and hand than currently available control methods.
Future work will focus on confirming these results in
subjects with amputation and refining the techniques.
