Explanation:
Detailed explanation-1: -The gauge factor value is influenced by the variation of the piezoresistive conductor resistivity and by its dimensions’ variations (longitudinal and transversal) provoked by its lengthening, depending on. Equation 4.5.
Detailed explanation-2: -Gauge Factor: The gauge factor is defined as the ratio of per unit change in resistance to per unit change in length. It is a measure of the sensitivity of the gauge. The above equation is valid only when the Piezoresistive effect that changes in resistivity due to strain is almost neglected.
