Microfiber transducer

Subscribe to changes of project pages

If you like what you see, don't just copy our technology, join SENSORICA. It is in your best interest! Here's why


The microfiber transducer is an optical fiber-based displacement/force transducer. It is fabricated by pulling an optical fiber to  only a few microns in diameter. Different optical fibers are used. The microfiber thus obtained is sensitive to microbending. 
It is used in the Mosquito sensor along with other types of displacement/force transducers. 


Short-term goals

  • test a few designs
  • model and optimize the transducer
  • design a transducer fabrication device

Long-term goals

Integrate with the Mosquito


understand how it works and optimize
design manufacturing process


Tibi (fabrication and optimization), Ivan (testing)

  • Why we should explore microfiber transducers Our recent results with the joint-type transducer and the constriction transducer tell us that in order to reach cellular level sensitivity we need to explore microfibers.
