material that reduce the voltage over distance

Nov 2019
I am working on spcail gyro sensor and i need for it conductive that make the elctric voltage lower when the the distance of the conductive is big for exmple in 30cm lbetween the minos and plus the voltage will be 10v
and on 15 cm it will be 4 or 5 v . someone knows how can it be done and when can i get the material for it i need it to be chip .
