Scalable 4-D printed tactile sensor for the detection of shear forces in the aid of plantar measurements

A variety of sensing technologies have been proposed to measure loading on the plantar surface of the human foot. The majority have a single measurement axis, and few are designed with multiple measurement axes capable of monitoring both normal and shear stress. In this paper a low cost, biocompatible triaxial sensitive force sensor that can be implemented with a simple fabrication using inexpensive equipment is proposed.
