Isivamvo soxinzelelo se-semiconductor esisetyenziswa ngokuqhelekileyo sisebenzisa i-N-type silicon wafer njenge-substrate. Okokuqala, i-silicon wafer yenziwa ibe yi-elastic ethwele uxinzelelo kunye nejometri ethile. Kwindawo ethwele uxinzelelo kwi-silicon wafer, ezine zohlobo lwe-P-diffusion resistors zenziwe ngeendlela ezahlukeneyo zekristale, kwaye emva koko ibhulorho yeWheatstone enengalo ezine yenziwa ngezi zixhasi zine. Ngaphantsi kwesenzo samandla angaphandle, utshintsho lwamaxabiso okumelana luba yimiqondiso yombane. Le bhuloho ye-wheatstone enefuthe loxinzelelo yintliziyo yenzwa yoxinzelelo, ebizwa ngokuba yi-piezoresistive bridge (njengoko kuboniswe kuMfanekiso 1). Iimpawu zebhulorho ye-piezoresistive zilandelayo: ① amaxabiso okumelana neengalo ezine zebhulorho ziyalingana (zonke i-r0); ② Isiphumo se-piezoresistive yeengalo ezikufutshane zebhulorho zilingana ngexabiso kwaye zichasene nomqondiso; ③ Iqondo lobushushu bokumelana neengalo ezine zebhulorho ziyafana, kwaye zihlala zikwiqondo lobushushu elifanayo. Kumkhiwane. I-1, i-R0 yixabiso lokumelana ngaphandle koxinzelelo kwindawo yokushisa; I-RT yinguqu ebangelwa yi-coefficient yokushisa yokumelana (α) xa ubushushu buguquka; Υ Rδ lutshintsho lokumelana okubangelwa kuxinzelelo (ε); Umbane ophumayo webhulorho ngu-u=I0 Δ Rδ=I0RGδ (ibhulorho yomthombo wangoku rhoqo).

Apho i-I0 isoloko ingumthombo wangoku kwaye i-e isoloko ingumthombo wombane wombane. I-voltage ephumayo yebhulorho ye-piezoresistive ihambelana ngokuthe ngqo kwi-strain (ε) kwaye ayinanto yakwenza ne-RT ebangelwa yi-coefficient yeqondo lokushisa lokuchasana, elinciphisa kakhulu ukufudumala kweqondo lokushisa kwenzwa. Inzwa yoxinzelelo lwe-semiconductor esetyenziswa kakhulu yinzwa yokubona uxinzelelo lwamanzi. Isakhiwo sayo esiyintloko i-capsule eyenziwe nge-silicon ye-monocrystalline (njengoko kuboniswe kuMfanekiso 2). I-diaphragm yenziwe ibe yindebe, kwaye ngaphantsi kwendebe yinxalenye ephethe amandla angaphandle, kwaye ibhuloho yoxinzelelo yenziwe phantsi kwendebe. I-pedestal yeringi yenziwe nge-silicon enye yekristale imathiriyeli, kwaye emva koko i-diaphragm ibotshelelwe kwi-pedestal. Olu hlobo lwenzwa yoxinzelelo lunoncedo oluphezulu, umthamo omncinci kunye nokuqina, kwaye isetyenziswe ngokubanzi kwi-aviation, ukuhamba kwendawo, izixhobo ezizenzekelayo kunye nezixhobo zonyango.
