Ingaruka ya Piezoelectric

Iyo dielectrics imwe ihinduwe no gukoresha imbaraga mubyerekezo runaka, amafaranga atangwa hejuru yubuso runaka, kandi iyo imbaraga zo hanze zavanyweho, zisubira muri leta zitishyuwe.Iyi phenomenon yitwa ingaruka nziza ya piezoelectric.Iyo umurima wamashanyarazi ushyizwe mubyerekezo bya polarisiyasi ya dielectric, dielectric izabyara imashini ihindagurika cyangwa umuvuduko wubukanishi mubyerekezo runaka.Iyo amashanyarazi yo hanze akuweho, guhindura cyangwa guhangayika bizashira, ibyo bita ingaruka zinyuranye za piezoelectric.

Ikintu cya Piezoelectric

Piezoelectric sensor ni sensor yumubiri hamwe na sensor yumuriro.Ibikoresho bya piezoelectric bikunze gukoreshwa ni Shi Ying kristal (SiO2 _ 2) hamwe nubutaka bwa piezoelectric ceramics.

Piezoelectric ihoraho ya ceramique ya piezoelectric yikubye inshuro nyinshi iy'ikariso ya Shi Ying, kandi ibyiyumvo byayo ni byinshi.

1. ingaruka z'amashanyarazi

Iyo urumuri rumurikira ikintu, rushobora gufatwa nkumugozi wa fotone hamwe ningufu e ibisasu.Niba ingufu za fotone ari nini bihagije, electron imbere yibintu bizakuraho imbogamizi zimbaraga zimbere kandi bigira ingaruka zijyanye namashanyarazi, aribyo bita fotoelectric.

2) Mubikorwa byumucyo, ibintu byerekana ko kurwanya ibintu bihinduka byitwa ingaruka zamafoto yimbere, nka Photoresistor, Photodiode, Phototransistor na Phototransistor.

3) Bitewe numucyo, ikintu gitanga ingufu za electromotive mucyerekezo runaka, aricyo bita fotovoltaque phenomenon, nka selile yifotora (igikoresho cyunvikana kumwanya wumucyo wabaye hejuru yubuso).

2 Kurwanya amafoto

Iyo fotorezisti irabagirana numucyo, electron zirimuka kugirango zibyare electron-umwobo, ibyo bigatuma ubukana buto.Urumuri rukomeye, niko rugabanuka.Umucyo wibyabaye urazimira, electron-umwobo byombi irakira, kandi agaciro ko guhangana karagenda gahoro gahoro.

3. Umuyoboro wamafoto

Imiyoboro ifotora (Photodiode, Phototransistor, Phototransistor, nibindi) nibikoresho bya semiconductor.

4. Electroluminescence

Ikintu cya luminescence cyakozwe nibikoresho bikomeye bya luminescent munsi yumuriro wumuriro w'amashanyarazi bita electroluminescence.Electroluminescence ni inzira yo guhindura mu buryo butaziguye ingufu z'amashanyarazi mu mbaraga zoroheje.Diode itanga urumuri (LED) nigikoresho cya semiconductor electroluminescent igikoresho cyuzuye ibikoresho bidasanzwe.Iyo PN ihurira imbere ibogamye, ingufu zirenze zitangwa bitewe na electron-umwobo wongeyeho, urekurwa muburyo bwa fotone kandi ugatanga urumuri.
