文摘In this paper three important characteristics in piezoresistance for the orthotropic material are given and proved theoretically:(1) The piezoresistance on the principal axis of an orthotropic material is independent of shear strains/stresses, but correlated with the normal strains/stresses only;(2) On the principal axis of material, following relations between piezoconductivity and piezoresistivity exist η iikk =-(γ ii ) -2 ξ iikk =-(ρ ii ) 2ξ iikk λ iikk =-(γ ii ) -2 χ iikk =-(ρ ii ) 2χ iikk (3) A laminate composed of orthotropic laminae in different orientations is orthotropic for its average/effective properties.
