Tape sensor project

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


Develop and commercialize an open source optical bending sensorTwo types are in development:
  • Directional tape sensor
  • Low-cost tape sensor


  • Robotics: flexible robot limbs, feedback control of motion and increased precision and efficiency
  • Structures: monitoring flexing of large structures     

Short-term goals

  • Build directional sensor prototype based on 1mm PMMA DONE!
  • Build low-cost tape sensor prototype DONE!
  • Outreach campaign for the low-cost tape sensor in progress

Long-term goals



[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.]
