Arrays of piezoresistive sensors (PRS), which an often used for tactile sensing, suffer from crosstalk between adjacent elements that can alter the readings of the force applied. In this paper, the sources of errors, with specific reference to crosstalk and electronic circuitry used to scan the array, are examined. The solutions presented in the literature are discussed, evaluating their performance and errors. From this analysis, some guidelines can be derived for the use of scanning circuits.

Abstract
Arrays of piezoresistive sensors (PRS), which an often used for tactile sensing, suffer from crosstalk between adjacent elements that can alter the readings of the force applied. In this paper, the sources of errors, with specific reference to crosstalk and electronic circuitry used to scan the array, are examined. The solutions presented in the literature are discussed, evaluating their performance and errors. From this analysis, some guidelines can be derived for the use of scanning circuits.
