Why this technology ?

Technical and operational advantages 

 

  • ultra-small sensor (diameter <100 microns)
  • virtually unlimited length of delivery fiber 
  • high sensitivity (<1 um and 1 microN)
  • wide range of forces to measure (>200 microN)
  • high temporal resolution (us-ms) 
  • electronics has small footprint 
  • robust, user friendly and high throughput
  • insensitive to magnetic fields
  • material can be plastic or glass to accommodate attachment to various surfaces (can even be braided)
  • open software [modular, customizable, free updates]
  • available expertise for installation, training and service 

Full characterization is being done by Philippe Comtois

12 of 37

Applications - bending and force sensor

The MOSQUITO can measure: 

​

  • deformation of an object
  • force applied to an object

13 of 37

Applications - hockey stick sensor

  • why an optical sensor and not a piezo ?
    • bending
    • proof of concept of robustness of our tech
    • fun

Example of a complete system

MOSQUITO-based force measurement system, -

this is what we install at the Royal Victoria Hospital for Dr. Sabah Hussain

15 of 37

Applications (continued)

Based on all the advantages of optical sensors (size, magnetic field neutral, wide range of measurements, shock resistance), an alternative to the widely used piezoelectric strain gauge sensors in many fields:

​

  • precise mechanical automated assembling (robots)
  • surgical tools and robots
  • sensors for artificial limbs
  • flow and vibration sensors
  • surface quality control sensors

Other nice things to come...

17 of 37

is a community!

  • produces Commons 
  • is open and transparent, therefore ethical
  • justly rewards creativity and labor
  • is collaborative rather than competitive 

​

We need to redefine collaboration rules...

Possible collab.

Advantages  

Disadvantages

Using stent manufacturing technology.

?

  • using stent manufacturing know how and tools
  • can be mass produced
  • doesn't require plugging the fiber into the device

fix fiber on the 3D structure.

is

An open, decentralized, self-organizing value network. 

​

  • It is designed to facilitate the creation and the exchange of value. 
    • Facilitates collaboration and co-creation. 
    • Secures transactions and reduces transaction costs.
  • It is decentralized 
    • The process of decision-making is distributed. 
    • It is NOT based on power-relations, it is a value-based network. 
  • It is has a very low barrier to entry; it is open in that sense. 
  • Its structure constantly adapts to internal and environmental conditions. 

​

SENSORICA is partially a commercial entity, partially a gift economy. It creates solutions to our problems and, some of them, in the form of products or services, are exchanged on the market. But it also allows individuals and organizations to participate without expecting of financial compensation. SENSORICA offers the

right balance between passion and duty, between freedom and constraint. 

26 of 37

is

  • An ethical and humane organization, by its nature.  
  • A locus of practical knowledge about optical fiber sensing.
  • An organization ready for the know how economy
  • An organizations producing Commons. 
  • We bet on speed to market and flexibility rather than protection.  
  • We achieve speed by embracing open innovation through a network-to-teams structure.
  • We build capacity by network affiliation / association. 
  • We are only limited by our ability to coordinate our global network.
  • We use a contribution-based compensation model. 

​

This is our road map

Business Model 

  • Attract customers through a reputation for deep knowledge about optical fiber sensor technology and its applications
  • Apply optical fiber sensing know-how to develop rapid, innovative solutions to customer challenges and opportunities
  • Select members from a globally-distributed optical fiber sensor value network to collaborate on customer-sponsored teams  
  • Compensate performance based on peer-evaluated contributions
  • Publish results under a Creative Commons license for leveraged results and recharge the global value network
