Development of a sensitive flexible tactile sensor array for force detection applications in knee arthroplasty

A flexible pressure sensor with bendable and distortable sensor arrays for force detection in knee arthroplasty were fabricated and characterized. The internal pressure of prosthesis knee joint can be effectively detected through real-time detection for sensor array output voltages. The pressure device shows good repeatability, consistency, small hysteresis in large detection range and stability in dynamic response which indicate promising potential in applications of knee arthroplasty.
