Izinzwa ze-semiconderctor tsport zingahlukaniswa ngezigaba ezimbili, eyodwa isuselwa emthethweni ukuthi izici ze-I-υ of semiconductor pn Jenction (noma iSchottky Junction) ushintsho ngaphansi kwengcindezi. Ukusebenza kwale nto ebucayi yengcindezi akusizi kakhulu futhi akukaze kwathuthukiswa kakhulu. Enye inzwa esekelwe kumphumela we-semiconductor piezoresorive, okuyizinhlobo eziphambili ze-semiconductor sensor. Ezinsukwini zokuqala, ama-semiconductor strain gauges anamathele kakhulu ezintweni eziningi ukwenza izingcindezi ezahlukahlukene nezinto zokulinganisa izindwangu. Ngo-1960s, ngokuthuthukiswa kobuchwepheshe besifunda se-semiconductor ahlanganisiwe, inzwa yokucindezela kwe-semiconductor enomqondo wokuphambanisa njengoba kwenzeka into ye-piezoresistive. Lolu hlobo lwezinzwa lwengcebo lunesakhiwo esilula neluthembekile, akukho zingxenye ezishukumisayo ezihambisanayo, kanye nento enobuhlakani yengcindezi kanye nento ebanzi ye-sensor ihlanganiswe, evikela i-mehendical lag futhi igweme ukusebenza kwenzwa.

Umphumela wePiezoresorive we-semiconductor semiconductor unesimo esihlobene namandla angaphandle, okungukuthi, ukumelana (okumelelwa ngophawu ρ). Ukushintshwa okuhlobene kokumelana ngaphansi kwesenzo sokuxineka kweyunithi kubizwa ngokuthi i-piezoresistive coefflive, evezwa yi-π. Kuvezwe ngokwezibalo njenge-ρ / ρ = π σ.

Lapho Σ Ukushintshwa kwenani lokumelana (R / R) okubangelwa ukumelana kwe-semiconductor ngaphansi kwengcindezi kunqunywa ikakhulu ekushintsheni kokuqina, ngakho-ke ukuvezwa komphumela wePiezoresurive nakho kungabhalwa njenge-R / R = Πσ.

Ngaphansi kwesenzo samandla angaphandle, ukucindezelwa okuthile (σ) kanye ne-strain (ε) kukhiqizwa kumakristalu ama-semiconductor, kanye nobudlelwano phakathi kwabo kunqunywa yi-modulus (y) yezinto ezibonakalayo (y) zezinto ezibonakalayo, okungukuthi, y = σ / σ / σ / ε.

Uma umphumela we-PieZoresuries uvezwa yi-strain ku-semiconductor, ngu-r / r = jhe.

U-G ubizwa ngokuthi yi-Sensitivivivity Factor yeStussure Sensor, emele ukushintshwa kwesihlobo senani lokumelana ngaphansi kwezinkinga zeyunithi.

I-PieZoresoresistive Coofflic noma i-Sensitivity Factor iyipharamitha eyisisekelo yomzimba ye-semiconductor Piezoresureive Effect. Ubudlelwano phakathi kwabo, njengobudlelwano phakathi kwengcindezi nobunzima, kunqunywa yi-modulus yomancane yalokho okuqukethwe, okungukuthi, g = π y.

Ngenxa ye-anisotropy yamakristalu emigwende e-Elasticity, i-modulus kanye ne-piezoresoresivistive coeffleefly change nge-Crystal Orieffication. Ubukhulu be-semiconductor piezoresistive umphumela futhi uhlobene eduze nokumelana kwe-semiconductor. Ukwehlisa ukumelana, okuncane okuzwakalayo kokuzwela. Umphumela we-PieZoresistive wokumelana nokuphazamiseka kunqunywa ukuqondiswa kwe-crystal kanye nokungcola kokungamelana nokuphazamiseka. Ukuhlushwa ukungcola ikakhulukazi kusho ukungcola kokungcola kwesendlalelo se-diff.
