Weekly Update IV

Up till now almost all features have been completed except for pressure sensitivity.

I used arduino nano as my micro controller and two pressure sensors placed at the

front and at the back of the insole. A 9V battery was used to power the hardware.



  • Not enough space to embed the electronics in the insole
  • Lack of good¬†and cheap alternatives for supplying power
  • Limited budget, so couldn’t purchase more sensors.
  • Carving out the insole was difficult. The material is hard to work with
  • Reliability issues with arduino nano (a known issue, that I should have known before purchasing it !!)


  • Was able to get the device working
  • Was able to fit all the hardware in the insole and hide it using a black fabric
  • Even after modifications the design is relatively sleek and comfortable
