Ngaba ungasixelela ngakumbi malunga nefuthe letyuwa kwiziphumo?Ngaba kukho uhlobo oluthile lwempembelelo ye-capacitive ye-double layer ye-ion emhlabeni?
Kuya kuba kuhle ukuba ungandibonisa ulwazi oluninzi malunga noku.Ndinomdla wokwenza imilinganiselo yokufuma komhlaba echanekileyo.
Khawufane ucinge ukuba bekukho umqhubi ogqibeleleyo ojikeleze inzwa (umzekelo, ukuba isivamvo sintywiliselwe kulwelo lwentsimbi ye-gallium), besiya kudibanisa iipleyiti ze-capacitor ezizivayo omnye komnye, ukuze isigqubuthelo ekuphela kwento phakathi kwabo sibe yingubo ebhityileyo ehambelanayo. ibhodi yesekethe.
Ezi zivamvo zinexabiso eliphantsi, ezakhelwe kwiitshiphusi ezingama-555, zihlala zisebenza ngokuphindaphindiweyo kumashumi e-kHz, ephantsi kakhulu ukuphelisa impembelelo yeetyuwa ezinyityilisiweyo.Isenokuba phantsi ngokwaneleyo ukuba kubangele ezinye iingxaki ezifana nokufunxa i-dielectric, ezibonakalisa njenge-hysteresis.
Qaphela ukuba ibhodi ye-sensor ngokwenene i-capacitor kuchungechunge kunye nesekethe elinganayo yomhlaba, enye kwicala ngalinye.Ungasebenzisa kwakhona i-electrode engakhuselekanga ngaphandle kwengubo yokudibanisa ngokuthe ngqo, kodwa i-electrode iya kuchithwa ngokukhawuleza emhlabeni.Ukusetyenziswa kwentsimi yombane kuya kubangela i-polarization kumhlaba + kwindawo yamanzi.Imvume eyinkimbinkimbi ilinganiswa njengomsebenzi wombane osetyenzisiweyo, ngoko ke i-polarization yezinto eziphathekayo zihlala zilele emva kwendawo yombane esetyenzisiweyo.Njengoko i-frequency yentsimi esetyenzisiweyo isanda kuluhlu oluphezulu lwe-MHz, inxalenye yentelekelelo ye-dielectric eqhubekayo yehla ngokukhawuleza njengoko i-dielectric polarization ingasalandeli i-oscillations ephezulu yombane.
Ngaphantsi kwe-500 MHz, inxalenye ecingelwayo ye-dielectric constant ilawulwa yityuwa kwaye, ngenxa yoko, i-conductivity.Ngaphezulu kwezi zihlandlo, i-dipole polarization iya kuncipha kakhulu kwaye i-dielectric constant constant iya kuxhomekeka kumxholo wamanzi.
Uninzi lwabenzi boluvo zorhwebo luyicombulula le ngxaki ngokusebenzisa amaza asezantsi kunye nokusebenzisa igophe lokulinganisa ukulinganisa iipropati zomhlaba kunye nokuphindaphinda.
