Self-sensing tactile probe based on fiber segment interferometry in multicore fibers

Our latest publication shows the potential of fiber segment interferometry in multicore fibers for implementing tactile sensors with low cost and high resolution. Using the Fresnel reflections at cleaved fiber endfaces - a simple piece of multicore fiber can be used as sensor for lateral force and displacement. We were able to show, that with this simple kind of tactile probe, noise levels of 0.6 nm∕√Hz for lateral displacement or 0.6 nN∕√Hz for lateral forces can be achieved, highlighting the potential for tactile probing in various fields. We are happy to publish these results in the renowned "Measurement" journal. Find the full-text here!
