Force torque sensor that can be integrated into prosthetics or exoskeletons, enabling lighter-weight constructions.

For most prosthetics, available sensors employ strain gauges which measure micro-scale deformations in a structure. These sensors are often optimized for high accuracy and precision, but have a large size and need external electronics, increasing the weight and bulk of prosthetics.

University of Utah researchers have developed a force torque sensor that integrates into powered lower limb prosthetics. The force toque sensor consists of magnetic sensors that measure micro-scale deformations in a structure with integrated electronics, enabling lighter-weight and smaller prosthetics and exoskeletons.

Pre-Clinical Validation

• Lighter torque sensor enables smaller exoskeletons and prosthetics.

• Requires less electronic hardware.
