Inzwa yesikhundla se-capacive

I-1.Capaciousitive yesikhundla sensor iyinhlangano engeyona eyokuxhumana, okuvame ukuqukethe izingxenye ezintathu: indawo yokutholwa, ungqimba oluvikela kanye negobolondo. Bangalinganisa isikhundla esiqondile selitshe, kepha kuphela into. Uma into elinganisiwe ingaqhubi, iselusizo ukukala ubukhulu noma ubukhulu.

2.Kwakukukala kwento evuthayo, isinali yokuphuma akuhlangene nalutho lwento, ngoba inzwa yokufudumala, bonke abaqhubi bayi-electrode efanayo. Lolu hlobo lwe-sensor lusetshenziswa ikakhulukazi ku-disk drive, ubuchwepheshe be-semiconductor kanye nokulinganiswa okuphezulu kwezimboni, kepha kudinga ukunemba okuphezulu kakhulu kanye nokuphendula imvamisa. Lapho isetshenziselwa ukukala abaqhubi, izinzwa zesikhundla ze-capacive zivame ukusetshenziswa ukuthola amalebula, ukumboza bese ulinganisa ubukhulu bephepha noma ifilimu.

I-3.Capacipitive isikhundla sen Sensor yasetshenziswa ekuqaleni ukukala ibanga lokufuduka eliqondile, lisukela kumamilimitha ambalwa liye kuma-nanometers amaningana, futhi ukulinganisa kwaqedwa ngokusebenzisa izici zikagesi zokuvuselelwa. Amandla ento okufanele uyigcine ibizwa ngokuthi yi-Capicacitance. Idivaysi evamile ye-capacitor yokukhokhisa i-capacitor yeplate. I-Capacitance ye-Plate Capacitor ilingana ngqo nendawo ye-electrode kanye ne-dielectric njalo, futhi ilingana kakhulu nebanga phakathi kwama-electrode. Ngakho-ke, lapho ibanga phakathi kwe-electrodes lishintsha, amandla nawo ayashintsha. Egama elithi, inzwa yesikhundla se-capacive usebenzisa lesi sici sokuthola isikhundla esiphelele.

I-4.A I-Sensor ejwayelekile yesikhundla se-capacive ifaka ama-electrodes amabili wensimbi, emoyeni njenge-dielectric. I-electrode eyodwa yenzwa yensimbi yensimbi, kanti enye i-electrode ye-capacitor yakhiwe ngento evuthayo ezotholwa. Lapho i-voltage isetshenziswa phakathi kwamapuleti wesifundo, insimu kagesi isungulwe phakathi kwamapuleti, futhi amapuleti amabili agcina izindleko ezinhle namacala amabi ngokulandelana. Inzwa ye-capacive isikhundla ngokuvamile yamukela i-ac voltage, eyenza inkokhiso epuletini ishintsha njalo, ngakho-ke ukuguqulwa kwesikhundla esiqondiwe kungatholwa ngokulinganisa amandla phakathi kwamapuleti amabili.

I-CAGASITITANACE inqunywa ibanga phakathi kwamapuleti, i-dielectric ihlala njalo i-dielectric nebanga phakathi kwamapuleti. Ezinzwa eziningi, indawo kanye ne-dielectric ehlala njalo ipuleti ye-electrode ngeke iguquke, kuphela ibanga elizothinta amandla phakathi kwe-electrode nento eqondiwe. Ngakho-ke, ukuguqulwa kwe-capacitance kungakhombisa isikhundla esiqondiwe. Ngokulinganisa, isiginali yeVoltage Volfage ye-Sensor inobudlelwano obuqondile nebanga phakathi kwebhodi lokutholwa kanye nelitshe. Lokhu kuzwela kwenzwa. Kukhombisa isilinganiso sokuphuma kweVoltage Shintsha ukuze sishintshe. Iyunithi imvamisa i-1v / micron, okungukuthi, i-voltage voltage eshintsha 1V njalo ngama-microns ayi-100.

6. Lapho kufakwa i-voltage endaweni yokutholwa, insimu kagesi esetshenzisiwe izokhiqizwa entweni etholakele. Ukuze unciphise ukuphazamiseka, kufakwa ungqimba oluvikelayo. Kusebenza amabutho afanayo we-elektromotive kuwo womabili ama-Exs wendawo yokutholwa ukuvikela insimu kagesi endaweni yokutholwa kusuka ekuvuzeni. Abaqhubi bangaphandle kwezinye izindawo zokutholwa bazokwakha insimu kagesi ngongqimba oluvikelayo futhi ngeke baphazamise inkambu kagesi phakathi kwelitshe nendawo yokutholwa. Ngenxa yesendlalelo sokuvikela, insimu kagesi endaweni yokutholwa yi-conical. Indawo evikelwe yinsimu kagesi ekhishwe yi-electrode yokutholwa yi-30% enkulu kunendawo yokutholwa. Ngakho-ke, indawo yobubanzi yento etholakele kumele okungenani ibe yinkulu engama-30% kunendawo yokutholwa kwenzwa.
