Intrinsic transducer

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


Design intrinsically bend-sensitive optical fiber for very sensitive displacement/force sensors.  

See more on the ENGAGE grant application

Optical Fiber Based Displacement-Force Sensors


Short-term goals

  • Get an ENGAGE grant for development - DONE!!

Long-term goals

Have different fiber recipes and a fabrication facility OR a supplier. 


  • Explore a few different designs and chose a few of those
  • Fabricate a few types of bend-sensitive fiber, different diameters are required
  • Perform opto-mechanical characterization of the fiber 
  • Integrate new fiver into the Mosquito 


  • Paper - Photonic bandgap Bragg fiber sensors for bending/displacement detection SENSORICA members in collaboration with Maksim Skorobogatiy and Hang Qu, from Ecole Polytechnique de Montreal.

  • Zemax simulation of MM fiber bending loss Recently, Hang Qu used Zemax to simulate the fiber bending sensor based on a regular multimode fiber. Here are some of his conclusions: Zemax is capable to simulate the bending ...

[This list will be replaced with a UI/script which will automatically pull info from the activity log, and display members
involved and their relative contribution. See infrastructure activity cluster for more on infrastructure development.]


Revenue will be generated by selling transducers. Transducers are consumables, they have a finite life-time and they need to be replaced from time to time. Transducers are used in the Mosquito, and other systems that integrate the Mosquito. 
  • All members involved in design and prototyping of the transducer will be compensated from the income generated by sales, in proportion with their involvement. Any future improvement of theconstriction transducer will be accounted for.
  • Members taking part in designing and building the semi-automated manufacturing device to assemble our transducers will also have a cut from the revenue generated by every transducer sold. 
  • Members involved in the manufacturing process will get compensated according to the amount of time they put in for every batch of transducers sold.
