Design and performance of a Fiber Bragg grating displacement sensor for measurement of movement

The Innovation

A displacement sensor that accurately measures changes in the length of ligaments under various dynamic conditions and is a useful indicator of soft-tissue loading. It measures the deformation of mechanical structures during application of loads.

Competitive Edge

The sensor is extremely light-weight, compact, accurate and repeatable.

Targeted Market

Any application where measurement of movement is desired, such as Achilles tendon tests and measuring ligament strains in the knee.
