Piezoelerric zotsatira

Ngati ndalama zina zimasiyidwa pogwiritsa ntchito mphamvu inayake, milandu imapangidwa pamtunda wina, ndipo pamene mphamvu yakunja imachotsedwa, abwerera ku dziko losagwirizana. Izi zimatchedwa kuti piezoelecric zotsatira. Ndondomeko yamagetsi ikagwiritsidwa ntchito polandation ya polarric ya dielectric, diectric idzatulutsa makina osokoneza makina kapena kukakamizidwa m'njira inayake. Pomwe munda wamagetsi wakunja utachotsedwa, kusokonekera kapena nkhawa kumatha, zomwe zimatchedwa kuti piezoelelerric zotsatira.

Piezoelectric Element

Piezoelectric sensor ndi sensor yolimbitsa thupi komanso sensa yamphamvu. Zithunzi zomwe zimagwiritsidwa ntchito pompoezoelectric ndi shi y ring rystal (siio2 _ 2) ndi kupanga piezoelect ceramics.

Piezoelerric nthawi zonse ya piezoelect amakhala kangapo kwa Shing Crystal, ndipo khutu lake ndi lalitali.

4) trawmelectric transducer

1.

Pamene kuwala kumalepheretsa chinthu, kumatha kuwonedwa ngati zingwe za zithunzi ndi mphamvu e ifgy ext chinthucho. Ngati mphamvu za actons ndi zokulirapo mokwanira, ma elekitoni mkati mwake amachotsa zopinga zamkati ndikukhala ndi zofanizira zamagetsi, zomwe zimatchedwa Putoelectric zotsatira.

1) Pansi pa zopepuka, izi zimatuluka kuchokera pamwamba pa chinthu zimatchedwa chithunzi chakunja, monga pyamelectric chubu cha chubu ndi Photomaltipter.

2) Pansi pa ntchito yopepuka, izi zimapangitsa kuti chinthu cha chinthu chosagwirizana, monga a Photootodistor, Phototransistor ndi Phototransistor.

3) Pansi pa ntchito yowunikira, chinthu chimatulutsa mphamvu zamagetsi m'njira inayake, yomwe imatchedwa Photovoltaic Phenomenon Phenomenon Phenomenon Phenomenon Phenomenon Phenomenon Phenomenon PHENVEENONE PHENOMENONE PHEENTEENT Cell (chida chowoneka bwino pamtunda).

2 Wosasamala

Monga momwe chithunzi cha iloressistar chimakhala chowala, ma elekitoni amasamukira kuti apange ma elekitironi a elekitron-hole, omwe amapangitsa kuti kukhale komweko Olimba kuwala, kutsitsa kukana. Kuwala kwa chochitikacho kumazimiririka, mabowo a electron-hole amapambana, ndipo mtengo wotsutsana pang'onopang'ono amabwerera pamtengo wake.

Ma tubes okutira (Photoodide, Phototransistor, PhotoonAnsIstor, etc.) kukhala zida semiconduct.

4. Ma Eleartuminescence

Zowopsa zopangidwa ndi zinthu zolimba zopangidwa pansi pa chitsirizidwe cha gawo lamagetsi zimatchedwa magetsi. Magetsi ndi njira yosinthira mphamvu yamagetsi kuti ikhale mphamvu yamagetsi. Diide yopepuka (LED) ndi semiconductoctor elecroumeinescent chida chomwe chimapangidwa ndi zida zapadera. Pamene pn Junction ndi mtsogolo, mphamvu zochulukirapo zimapangidwa chifukwa cha kusungo kwa eleki ya electron, komwe kumatulutsidwa mu mawonekedwe a zithunzi ndikuwunika kuwala.
