• Sucesses : It worked well for either when it is bended and even when it goes back to the initial state.
  
• Problems : The led a little blinked. I assumed that the unstable connection was because the conductive thread stitches had small abount of contact area with Velostat.
  

Prototype 3

To enlarge the contact area, I replaced conductive thread with conductive fabric and widened the sensor. In this time, I also folded the piece of Velostat to make stronger arch.
