A new and unique strain sensing
solution based on Polymer Optical Fibers (POF) provides designers with
a low-cost sensing solution that is lightweight, immune to
electromagnetic interference (EMI) and electromagnetic susceptibility
(EMS) and does not require electrical current at the sensing point.
The unique, cost-effective POF based strain sensor solution is based on a patented Optical Phase Interrogation (OPI) technique developed by Avago Technologies. It enables readily available POF to be used as a high-precision strain sensor on par with current Fiber Bragg Grating (FBG) based strain sensors. The strain sensor is now available from AMS Technologies across Europe. Click here for more

The strain sensor using POF is a
worthy alternative to conventional electrical and optical strain
sensing technologies. Strain gauge and accelerometer solutions require
power to be brought to the sensor, which limits where the sensors can
be applied, whereas the POF based sensor does not require electrical
current at sensing point. Optical strain measurement systems, such as
Fiber Bragg Gratings (FBG), have been commercially available for a
number of years, but Bragg based solutions are significantly more
expensive and complex to install.
