RALEIGH – A soft, flexible sensor system created with electrically conductive yarns could help map problematic pressure points in the socket of an amputee’s prosthetic limb, researchers from North Carolina State University report in a new study.
In
IEEE Sensors Journal, researchers from North Carolina State University reported on the lightweight, soft textile-based sensor prototype patch. The device incorporates a lattice of conductive yarns and is connected to a tiny computer. They tested the system on a prosthetic limb and in walking experiments with two human volunteers, finding the system could reliably track pressure changes in real time.
