After extensive research and testing of different materials like rubber, which I realized was too thick to be worn snugly on the bottom of the foot, I decided to print a film sensor with electrically conductive pressure-sensitive ink particles.
Nakon iscrpnog istraživanja i testiranja raznih materijala poput gume, za koju sam shvatio da je predebela da bi se nosila pripijena za stopalo, odlučio sam isprintati filmski senzor s električki provodnim česticama tinte  osjetljiv na pritisak.
