Semiconductor Imodoka Yumuvuduko Imyandikire irashobora kugabanywamo ibyiciro bibiri, umuntu ashingiye ku ihame ryo I-υ riranga PN Imikorere yiki gituro ibintu byoroshye ntabwo ihindagurika kandi ntabwo yakuze cyane. Undi ni sensor ashingiye ku ngaruka ya Semiconductor ingaruka, niyo mpamvu nyamukuru zitandukanye za semiconductor yumuvuduko wumuvuduko. Mu minsi ya mbere, Secokonductor Stin Gauges yari ifatanye ahantu hamwe n'ibikoresho bitandukanye no gupima ibikoresho. Mu 1960, hamwe n'iterambere rya semiconductor ikoranabuhanga mu muzunguruko, semiconductor ya semiconductor hamwe no kurwanya ikwirakwizwa mu gihe ikintu cya Pienzoresilasite cyagaragaye. Ubu bwoko bwigitutu bufite imiterere yoroshye kandi yizewe, nta bice byimuka byumwigendera hamwe nibintu byigituba bya sensor byinjijwemo, byirinda imikorere ya sensor kandi itezimbere imikorere ya sensor.

Ingaruka ya Piezoresuctor ya Semiconductor semiconductor ifite ibiranga ingufu zibintunze hanze, ni ukuvuga, ingwate (ihagarariwe na syt stress ρ, bikagira ingaruka nziza. Guhindura abantu barwaye mubihe byimihangayiko byitwa piezoresiteve coeefficial, bigaragazwa nikimenyetso Π. Yerekanye imibare nka ρ / ρ = Π σ.

Aho σ yerekana imihangayiko. Guhindura agaciro karwanywa (R / R) biterwa na semiconductor iterwa no guhangayika cyane cyane bigenwa no guhindura itandukaniro, bityo imvugo yingaruka ya Piezorestive nayo irashobora kandi kwandikwa nka R / R = πσ.

Under the action of external force, certain stress (σ) and strain (ε) are generated in semiconductor crystals, and the relationship between them is determined by Young's modulus (Y) of the material, that is, Y=σ/ε.

Niba ingaruka za piezorestive zigaragazwa numurimo kuri semiconductor, ni r / r = gε.

G yitwa imyumvire yubwenge ya sensor yumuvuduko, igereranya guhindura igereranya agaciro irwanya igice.

Piezoresistive coeffice cyangwa imitekerereze yibipimo byibanze byumubiri bya semiconductor demicoresistive. Umubano hagati yabo, nkumubano hagati yintege nke no guhangayika, bigenwa na modulus yikirere yibikoresho, ni ukuvuga G = Π y.

Kubera Anisotropie ya Semiconductor Crystals muri elarist, modulus ya modulus na piezoresite ihinduka hamwe na kristal icyerekezo. Ubunini bwa Semiconductor ingaruka za Pimicorestive nanone bifitanye isano rya bugufi no kurwanya semiconductor. Hasi yo kurwanya, ibintu bito byubwenge. Ingaruka ya Piezorestive yo kurwanya ikwirakwizwa bigenwa na kirimbuzi ya kirisiti no guhuriza hamwe ibitekerezo byo kurwanya ikwirakwizwa. Ubuhumyi bwanduye bugaragaza cyane cyane umwambare wibanda kubice bitandukanye.
