Umuyoboro wa Semiconductor urashobora kugabanywamo ibyiciro bibiri, kimwe gishingiye ku ihame ryerekana ko I-υ ibiranga semiconductor PN ihuza (cyangwa ihuriro rya schottky) ihinduka mukibazo.Imikorere yibi bintu byoroshye ntabwo ihindagurika kandi ntabwo yateye imbere cyane.Ibindi ni sensor ishingiye kuri semiconductor piezoresistive ingaruka, nubwoko nyamukuru bwimyanya ndangagitsina.Mu minsi ya mbere, ibipimo byifashishwa bya semiconductor byashyizwe ahanini mubintu byoroshye kugirango bikore ibintu bitandukanye hamwe nibikoresho byo gupima.Mu myaka ya za 1960, hamwe niterambere rya semiconductor ihuriweho na tekinoroji yumuzunguruko, icyuma gikoresha ingufu za semiconductor hamwe na diffuzistoriste ikwirakwizwa nkibintu bya piezoresistive byagaragaye.Ubu bwoko bwumuvuduko wumuvuduko ufite imiterere yoroshye kandi yizewe, nta bice bigenda byimuka, hamwe nibintu byoroha byumuvuduko nibintu bya elastike ya sensor birahujwe, birinda gukererwa gukanika no kunyerera kandi bitezimbere imikorere ya sensor.

Ingaruka ya Piezoresistive ya semiconductor Semiconductor ifite ibiranga bifitanye isano nimbaraga zo hanze, ni ukuvuga, kurwanya (kugereranwa nikimenyetso ρ) guhinduka hamwe na stress ifite, aribyo bita piezoresistive effect.Impinduka zijyanye no guhangana nigikorwa cyo guhangayikishwa nigice cyitwa coefficient piezoresistive, igaragazwa nikimenyetso π.Kugaragaza imibare nka ρ / ρ = π σ.

Aho σ byerekana guhangayika.Guhindura agaciro kokurwanya (R / R) guterwa no kurwanya semiconductor mukurwanya stress bigenwa cyane cyane nihinduka ryokurwanya, bityo imvugo yingaruka za piezoresistive nayo ishobora kwandikwa nka R / R = πσ.

Mubikorwa byimbaraga zo hanze, guhangayika (σ) hamwe ningutu (ε) bibyara muri kristu ya semiconductor, kandi isano iri hagati yabo igenwa na modulus ya Young (Y) yibikoresho, ni ukuvuga Y = σ / ε.

Niba ingaruka ya piezoresistive igaragazwa ningutu kuri semiconductor, ni R / R = Gε.

G yitwa sensibilité yibintu byumuvuduko ukabije, byerekana ihinduka ryagereranijwe ryagaciro kangana kurwego.

Coefficient ya Piezoresistive cyangwa sensibilité nibintu byingenzi byibanze byumubiri wa semiconductor piezoresistive ingaruka.Isano iri hagati yabo, kimwe nubusabane hagati yo guhangayika no guhangayika, bigenwa na Modulus yumusore wibikoresho, ni ukuvuga g = π y.

Kuberako anisotropy ya semiconductor kristaliste muri elastique, Modulus yumusore hamwe na coefficient ya piezoresistive ihinduka hamwe na kristu yerekanwe.Ubunini bwa semiconductor piezoresistive ingaruka nabwo bufitanye isano rya bugufi no kurwanya semiconductor.Hasi yo kurwanya, niko ibintu bito byoroha.Ingaruka ya piezoresistive yo kurwanya ikwirakwizwa igenwa nicyerekezo cya kristu hamwe nubushuhe bwimyanda yo kurwanya ikwirakwizwa.Kwibanda kwumwanda ahanini bivuga ubusumbane bwubuso bwibintu byo gukwirakwiza.
