Mmetụta piezoelectric

Mgbe ụfọdụ dielectrics na-emeziwanye site n'itinye ike na ntụziaka ụfọdụ, a na-emepụta ụgwọ n'elu elu, ma mgbe a na-ewepụ ike dị n'èzí, ha na-alaghachi na steeti a na-akwụghị ụgwọ. A na-akpọ ihe omume a nke ọma mmetụta piezoelectric. Mgbe a na-etinye ọkụ eletrik na ntụziaka polarization nke dielectric, dielectric ga-emepụta nrụrụ igwe ma ọ bụ nrụgide ígwè ọrụ n'akụkụ ụfọdụ. Mgbe e wepụrụ oghere eletrik dị n'èzí, nrụrụ ma ọ bụ nrụgide ga-apụ n'anya, nke a na-akpọ mmetụta piezoelectric inverse.

Piezoelectric mmewere

Ihe mmetụta Piezoelectric bụ ihe mmetụta anụ ahụ yana ihe mmetụta ike ike. Ihe eji eme piezoelectric a na-ejikarị bụ Shi Ying crystal (SiO2 _2) na seramiiki piezoelectric sịntetik.

Piezoelectric mgbe niile nke ceramics piezoelectric bụ ugboro ugboro nke Shi Ying kristal, na uche ya dị elu.

4) transducer fotoelectric

1. mmetụta fotoelectric

Mgbe ìhè na-amụba ihe, enwere ike iwere ya dị ka eriri foton nwere ike e bombarding ihe. Ọ bụrụ na ike nke photons buru ibu, electrons dị n'ime ihe ahụ ga-ewepụ ihe mgbochi nke ike dị n'ime ma nwee mmetụta eletrik kwekọrọ, nke a na-akpọ mmetụta fotoelectric.

1) N'okpuru ọrụ nke ìhè, ihe na-eme na electrons na-agbapụ n'elu ihe a na-akpọ mmetụta fotoelectric mpụga, dị ka tube foto na fotomultiplier tube.

2) N'okpuru omume nke ìhè, a na-akpọ ihe na-agbanwe agbanwe nke ihe a na-akpọ mmetụta photoelectric dị n'ime, dị ka photoresistor, photodiode, phototransistor na phototransistor.

3) N'okpuru ọrụ nke ìhè, ihe na-emepụta ike electromotive na ụfọdụ ntụziaka, nke a na-akpọ fotovoltaic phenomenon, dị ka fotovoltaic cell (ngwaọrụ na-emetụ n'ahụ ọnọdụ nke ihe merenụ ìhè ntụpọ n'elu photosensitive elu).

2 resistor mmetụta foto

Mgbe ọkụ na-agbapụta fotoresistor, electrons na-akwaga iji mepụta ụzọ abụọ-oghere eletrọn, nke na-eme ka mgbochi ahụ dị ntakịrị. Ka ọkụ na-esiwanye ike, na-ebelata nguzogide. Ìhè ahụ merenụ na-apụ n'anya, ụzọ abụọ-oghere eletrọn na-agbake, na uru nguzogide na-eji nwayọọ nwayọọ laghachi na uru mbụ ya.

3. Photosensitive tube

Ọkpụkpọ foto (photodiode, phototransistor, phototransistor, wdg) bụ nke ngwaọrụ semiconductor.

4. Electroluminescence

Ihe ngosi luminescence mepụtara site na ihe ndị siri ike luminescent n'okpuru mkpali nke ọkụ eletrik ka a na-akpọ electroluminescence. Electroluminescence bụ usoro ịtụgharị ọkụ eletrik ozugbo ka ọ bụrụ ike ọkụ. Igwe ọkụ na-emitting diode (LED) bụ ngwaọrụ semiconductor electroluminescent nke ejiri ihe pụrụ iche dochie ya. Mgbe njikọ PN na-aga n'ihu na-adịghị mma, a na-emepụta ike dị ukwuu n'ihi nchikota oghere eletrọn, nke a na-ewepụta n'ụdị foton ma na-ebunye ọkụ.
