Semiconductor kumanikidza sensors inogona kukamurwa kuita mapoka maviri, imwe inoenderana neiyo nheyo yekuti ini-den hunhu hweSemiconductor PN Junction) shanduko yekumanikidzwa. Kuita kwekumanikidza uku kwakareruka chinhu hakusi kugadzikana uye hakuna kugadzirwa kwazvo. Iyo imwe ndeye sensor yakavakirwa paSemiconductor piezoresistive mhedzisiro, inova iyo huru dzakasiyana-siyana semiconductor kumanikidza sensor. Mumazuva ekutanga, Semiconductor Strain Gauges ainyanya kubatanidzwa kune elastic zvinhu kuti aite kushushikana kwakasiyana-siyana uye kushushikana kwekuyera kuyera. Muna 1960s, nekuvandudzwa kweSemiconductor Circrick Circulogy, Semiconductor Pronet Sensor ine difFulion Service sePizoResistive element yakaoneka. Rudzi urwu rwekumanikidza sensor zvine chimiro chakareruka uye chakavimbika

PiezoResistive Mhedzisiro yeSemiconductor Semiconductor ine hunhu hune chekuita nesimba rekunze, kureva kuti, inomiririrwa nechiratidzo ρ) inoshandura nekushushikana kwayo, iyo inonzi Piezoresisival. Shanduko yehukama yebasa iri pasi pechiitiko cheyuniti kushungurudzika kunonzi PiezoResistive coefferist, iyo inoratidzwa nechiratidzo π. Yakaratidza mathematics se ρ / ρ = π σ.

Iko σ inomiririra kushushikana. Shanduko yekudzivisa kukosha (r / r / r) yakakonzerwa kupokana pasi pekushushikana kunonyanya kutsanangurwa nekushandurwa kwesporesisives, saka kutaura kwe piezoesisives kunogona kunyorwawo seR / r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r = r =

Pasi pechiitiko chesimba rekunze, kushushikana kwekunze, kushushikana (σ) uye kunetseka

Kana iyo piezesistive mhedzisiro inotaurwa nehuremu paSemiconductor, iri r / r = g.

G inonzi inonzi sensitivity sechinhu chekumanikidza sensor, iyo inomiririra shanduko yehukama yekudzivisa kukosha pasi peyuniti.

PiezoResistive coeff feacffient kana sensitivity sechinhu ndiyo yekutanga kwepanyama paramende ye semiconductor piezoctoryising. Hukama pakati pavo, sekufanana nehukama pakati pekushushikana uye kunetseka, kwakatemwa nemugadziri wechidiki wezvinyorwa, izvo, g = π y.

Nekuda kweiyo anisotropy ye semiconductor makristasi muElasticity, young's modulus ne piezousesistive coefferist shanduko nekristaro kutarisisa. Ukuru hweSemiconductor PiezoResistive Mhedzisiro zvakare zvine chekuita nePistist of Semiconductor. Iyo yakadzika pokana, iyo diki iyo sensitivity sechinhu. Iyo piePiezesistive mhedzisiro yekusiyana kwekushomeka inotsanangurwa neyekonyera kutarisisa uye kusarongeka kwekusiyana kwekuramba. Iko kusarongeka kwekusarongeka kunonyanya kureva pamusoro pewakasimudzirwa kusarudzika kweiyo kusarudzika kwedare.
