Ukushisa nengcindezi inzwa ye-Cummins 3408627

Umphumela wePiezoelectric

Lapho amanye ama-dielectric ekhubazekile ngokusebenzisa amandla endaweni ethile, amacala akhiqizwa endaweni ethile, kwathi lapho kususwa amandla angaphandle, abuyela esimweni esingalawulwanga. Le nto ibizwa ngokuthi yi-Piezoelectric Effect. Lapho insimu kagesi isetshenziswa ekuqondisweni kwe-polarization ye-dielectric, i-dielectric izokhiqiza ama-deformation mehendi noma ingcindezi yemishini endaweni ethile. Lapho kususwa insimu kagesi yangaphandle, i-deformation noma ukucindezela kuzonyamalala, okubizwa ngokuthi yi-Inverse Piezoelectric.

I-Piezoelectric Element

I-Piezoelectric Sensor inzwa yomzimba nenzwa yokungezelela amandla. Izinto ze-piezoelectric ezivame ukusetshenziswa yi-shi ying crystal (Sio2 _ 2) kanye nokwenza okwenziwe ngePiezoelectric ceramics.

I-piezoelectric ihlala njalo ye-piezoelectric ceramics inezikhathi eziningana ze-shi ying crystal, futhi ukuzwela kwayo kuphezulu.

4) I-PhotoElectric TransDerer

1. Umphumela We-Photoelectric

Lapho ukukhanya kwe-irradiatiates into, kungathathwa njengentambo ye-photons ene-energy e iqhuma into. Uma amandla e-photons amakhulu ngokwanele, ama-elektroni angaphakathi kwento azosusa izingqinamba zamandla angaphakathi futhi anemiphumela kagesi ehambisanayo, ebizwa ngokuthi yi-PhotoElectric.

1) Ngaphansi kwesenzo sokukhanya, into esebenza nge-elektroni abalekela ngaphandle kwento ibizwa ngokuthi yi-Photoelectric Cube yangaphandle, njenge-Photoelectric Tube ne-PhotoMultIer Tube.

2) Ngaphansi kwesenzo sokukhanya, into yokuvumisana okufundwa kwento ibizwa ngokuthi yi-PhotoElectric Effect yangaphakathi, njenge-PhotoDodes, PhotoDransistor kanye PhotoTransistor.

3) Ngaphansi kwesenzo sokukhanya, into ikhiqiza amandla e-electromotive endaweni ethile, ebizwa ngokuthi yi-Photovoltaic phenomenon, njenge-Photovoltaic cell (idivaysi ezwela isikhundla sendawo yokukhanya yesigameko).

2 UMSEBENZISO WOKUZIPHATHA KAKHULU

Lapho i-PhotoSeressor ixhumeka ngokukhanya, ama-elektroni afudumeza ukukhiqiza ama-elekthroni-hole pairs, okwenza ukumelana kube yincane. Ukukhanya okunamandla, okunciphisa ukumelana. Ukukhanya kwesigameko kuyanyamalala, kubuyisa ama-elektroni we-elektroni, kanye nenani lokumelana kancane kancane libuyela enanini layo lasekuqaleni.

I-3. I-tube yezithombe

Amashubhu we-Photosensitive (Photodiode, PhotoTransistor, PhotoTransistor, njll.) Amadivayisi we-Semiconductor.

4. ElectrolUminescence

Isimo se-luminescence esikhiqizwe ngezinto zokwenziwa eziqinile ze-luminescent ngaphansi kwe-expation of Electric field zibizwa ngokuthi i-electrollinancence. I-ElectrolISinescence inqubo yokuguqula ngokuqondile amandla kagesi ibe amandla akhanyayo. I-diode ekhipha ukukhanya Lapho i-PN Junction idluliselwe phambili, amandla ngokweqile akhiqizwa ukubuyiselwa kabusha kwe-elektroni, okukhishwe ngendlela yama-photons futhi akhiphe ukukhanya.
