SHUTE Sensing Solutions A/S produces all polymer fiber optic cables in-house. Polymer has obvious advantages to glass fiber regarding usage in human bodies. We are currently working together with partners on polymer fibers as part of bio mechanics projects. Another advantage is that SHUTE sensors work in highly magnetic environments, like MRI scanners.

How it works

SHUTE Sensing Solutions’ polymer fiber optic cables may be used as inner body communication wires in medical devices, transporting data to and from the med tech device and the human body.


SHUTE sensors can survive and function in high intencity magnetic fields: “We have tested the SHUTE mPOF sensor, and found it MRI/NMR compatible, it shows no sign of decrease in performance, when subjected to a gradient coil exercised with magnetic field strengths up to 1.5 T/m within a static main field of a 9.4 T super-conducting magnet. This paves the way for a whole new way of monitoring critical temperature values inside the MRI/NMR scanner environment.” says Palle Koch, Engineer, Dept. of Biomedical Sciences, University of Copenhagen.

In cooperation with the MR Research Centre at Aarhus University, SHUTE has tested its mPOF sensors inside a 3.0 Tesla GE Discovery MI scanner. "We wanted to test for respiration, motion detection, pulse and heart rate" SHUTE CTO Kristian Nielsen explains. The tests were performed on a 45 kilo, 3 months old, sedated pig inside a highly magnetic environment. "We had some fantastic results" Kristian Nielsen continues "The SHUTE fiber sensor bed patch easily detected respiration and even picked up a detailed pulse graph when the data was filtered." "Doing more tests with a SHUTE sensor patch on the chest of the pig, we saw clear pulse and heart rate movement."

The operating radiologist tried to detect the SHUTE fiber; but conclusion was, that the fiber image did not disturb any tests and he found the fiber virtually invisible. "To sum up, a perfect day of testing! All the tested SHUTE sensors performed perfectly in the high magnetic field" a satisfied CTO Kristian Nielsen concludes. Read more about it here: 'MRI Scanner Test Results June 2021'


Polymer fibers can also be used in other usage situations where mechanical properties are important. By combining polymer with surgical steel, even more robust fibers with different combinations of flexibility and stiffness can be achieved.
