Inzwa ye-semiconductor evame ukusetshenziswa kwe-semiconductor isebenzisa i-n-witri silicon wafer njenge-substrate. Okokuqala, i-Silicon wafer yenziwa engxenyeni ethe xaxa enengcindezi ene-geometry ethile. Engxenyeni ebhekene nengcindezi yesilicon wafer, ama-p-yp arvion amelana nokuphikiswa okwenziwe ngezindlela ezahlukene zekristalu, bese kudalwa ibhuloho le-wheattone elingama-wheatton nge-wheatton. Ngaphansi kwesenzo samandla angaphandle, izinguquko zamanani wokumelana abe yizimpawu zikagesi. Le bhuloho le-wheatstone elinomphumela wengcindezi liyinhliziyo ye-sensor yengcindezi, evame ukubizwa ngokuthi ibhuloho le-piezoresorive (njengoba kukhonjisiwe kuMfanekiso 1). Izici zebhuloho lePiezoresurive zimi ngalendlela elandelayo: ① Amanani okumelana nezingalo ezine zebhuloho ayalingana (wonke ama-R0); Umphumela we-PieZoresoresistive wezingalo eziseduze kwebhuloho ulingana ngenani futhi aphambene nesibonakaliso; ③ Ukuvikelwa kwezinga lokulinganisa kwezingalo ezine zebhuloho kuyafana, futhi zihlala zikushisa okufanayo. Ku-Fig. 1, R0 yinani lokumelana ngaphandle kwengcindezi ekushiseni kwegumbi; I-RT lushintsho olubangelwa i-coefficient yokushisa (α) lapho izinga lokushisa lishintsha; Υ Δ ukushintshwa kokumelana okubangelwa ubunzima (ε); I-voltage ye-voltage yebhuloho ngu-U = I0 δ rΔ rΔ = I0rgΔ (i-Retant Source Bridge).

Lapho i-I0 ihlala khona i-Source yamanje futhi e i-voltage Sound Voltage. I-voltage ekhishwayo ye-Piezoresustive Bridge ilingana ngqo nobunzima ( Inzwa ye-semiconductor esetshenziswa kakhulu ye-semiconductor iyinzwa yokuthola ingcindezi kagesi. Isakhiwo saso esiyinhloko yi-capsule eyenziwe nge-monocrystalline ailcon (njengoba kukhonjisiwe kuMfanekiso 2). I-diaphragm yenziwa enkomishini, futhi phansi kwendebe kuyingxenye ethwala amandla angaphandle, futhi ibhuloho lengcindezi lenziwa phansi kwendebe. Isisekelo sezindandatho senziwe ngezinto ezifanayo ze-silicon eyodwa Crystal impahla, bese i-diaphragm iboshelwe esisekelweni. Lolu hlobo lwezinzwa zokucindezela lunezinzuzo zokuzwela okuphezulu, ivolumu elincane nobumbano, futhi lusetshenziswe kabanzi ngendiza, navigation sendawo, amathuluzi ezokwelapha.
