Inzwa yokucindezela ye-semiconductor evame ukusetshenziswa isebenzisa i-N-type silicon wafer njenge-substrate.Okokuqala, isicwecwana se-silicon senziwa sibe yingxenye ethwala ukucindezeleka nge-geometry ethile.Engxenyeni ethwala ukucindezeleka yesinkwa esicwecwana se-silicon, izimelambisi ezine zohlobo lwe-P zokusabalalisa zenziwa ngezindlela ezihlukene zekristalu, bese kwakhiwa ibhuloho le-Wheatstone elinezingalo ezine ngalezi zinto ezine eziphikisayo.Ngaphansi kwesenzo samandla angaphandle, izinguquko zamanani okumelana ziba izimpawu zikagesi.Leli bhuloho le-wheatstone elinomphumela wokucindezela inhliziyo yenzwa yokucindezela, ngokuvamile ebizwa ngokuthi ibhuloho le-piezoresistive (njengoba kuboniswe kuMfanekiso 1).Izici zebhuloho le-piezoresistive zimi kanje: ① amanani okumelana nezingalo ezine zebhuloho ayalingana (wonke u-r0);② Umthelela we-piezoresistive wezingalo eziseduze zebhuloho uyalingana ngenani futhi okuphambene ngophawu;③ I-coefficient yokushisa yokumelana yezingalo ezine zebhuloho iyafana, futhi zihlala zisezingeni elifanayo.Emkhiwaneni.I-1, i-R0 inani lokumelana ngaphandle kokucindezeleka ekamelweni lokushisa;I-RT iwushintsho olubangelwa i-coefficient yokushisa yokumelana (α) lapho izinga lokushisa lishintsha;U-Υ Rδ ukuguqulwa kokumelana okubangelwa ubunzima (ε);I-voltage ephumayo yebhuloho ingu-u=I0 Δ Rδ=I0RGδ (ibhuloho lomthombo wamanje eliqhubekayo).

Lapho i-I0 ingumthombo wamanje wamanje futhi u-e ungumthombo we-voltage oqhubekayo.I-voltage ephumayo yebhuloho le-piezoresistive ilingana ngokuqondile ne-strain (ε) futhi ayihlanganise lutho ne-RT ebangelwa i-coefficient yezinga lokushisa lokumelana, okunciphisa kakhulu ukukhukhuleka kwenzwa.Inzwa yomfutho we-semiconductor esetshenziswa kakhulu iyinzwa yokubona umfutho wamanzi.Isakhiwo sayo esiyinhloko i-capsule eyenziwe nge-silicon ye-monocrystalline (njengoba kuboniswe kuMfanekiso 2).I-diaphragm yenziwa inkomishi, futhi phansi kwendebe ingxenye ephethe amandla angaphandle, futhi ibhuloho lokucindezela lenziwa phansi kwendebe.I-pedestal yeringi yenziwe ngento efanayo ye-silicon single crystal, bese i-diaphragm iboshelwa esisekelweni.Lolu hlobo lwenzwa yokucindezela lunezinzuzo zokuzwela okuphezulu, ivolumu encane nokuqina, futhi lusetshenziswe kabanzi ekundizeni, ukuzulazula emkhathini, amathuluzi azenzakalelayo namathuluzi ezokwelapha.
