Cov tshuab hluav taws xob hluav taws xob muaj peev xwm tsim tau ntau yam kev hloov pauv tam sim no. Nyob ntawm cov txiaj ntsig kev kho mob xav tau, cov txheej txheem sib txawv tuaj yeem siv los tsim cov ntaub so ntswg sib txawv. Kev nkag siab txog txoj hauv kev uas lub tshuab hluav taws xob hluav taws xob tuaj yeem hloov kho tam sim no yog qhov tsim nyog kom nkag siab zoo txog cov kev xaiv muaj rau tus kws phais neeg.
Ib qho tam sim no tuaj yeem raug cais raws li ncaj qha tam sim no lossis hloov pauv (sib txawv) tam sim no. Kev ncaj qha tam sim no tsis tu ncua, tsis hloov pauv (polarity) lossis qhov loj. Ncaj qha tam sim no yog hom tsim los ntawm roj teeb. Nws tsis yog siv hauv kev phais mob vim tias nws muaj peev xwm tsim kev tshem tawm ntawm cov leeg thiab cov leeg nqaij.
Kev hloov pauv tam sim no yog lub npe vim tias nws cov kev taw qhia (polarity) hloov pauv (hloov pauv). Hom hluav taws xob tam sim no zoo ib yam los ntawm cov hluav taws xob phab ntsa. Qhov nrawm uas qhov kev taw qhia ntawm kev hloov pauv tam sim no ib ntu ntawm lub sijhawm raug xa mus rau zaus, thiab ntsuas hauv Hertz (Hz). Ib lub voj voog ua tiav ib pliag yog ib Hz. Yog tias tam sim no hloov pauv polarity ib lab zaug ib pliag, nws yog ib qho megahertz (MHz) tam sim no. Cov tshuab hluav taws xob hluav taws xob feem ntau ua haujlwm ntau zaus ntawm 400,000 Hz thiab 2.5 MHz, txawm hais tias qee lub tshuab hluav taws xob tsim hluav taws xob nrog cov zaus ntau npaum li 3.5 MHz. Vim tias cov zaus no poob hauv qhov ntau ntawm cov xov tooj cua yoj, cov tshuab hluav taws xob hluav taws xob qee zaum hu ua cov tshuab hluav taws xob ntau zaus, thiab ua qhov tseeb, tsim cov xov tooj cua tsis yog khoom siv. Tog twg los ntau dhau lossis qis zaus tuaj yeem ua rau muaj kev cuam tshuam tsis zoo. Depolarization ntawm cov ntaub so ntswg raug tso tseg ntawm zaus ntau dua 10,000 Hz. Ntau zaus ntau zaus yuav txhawb kom muaj kev xau tam sim no.
Waveforms tuaj yeem hloov pauv los ntawm kev sib npaug ntawm ob lossis ntau lub cim, txheej txheem hu ua kev hloov pauv. Damped thiab blended currents yog piv txwv ntawm cov txheej txheem no. Muaj peb yam yooj yim ntawm cov qauv siv hluav taws xob tam sim no siv hauv kev kho hluav taws xob: txiav tam sim no, coagulation tam sim no, thiab sib xyaw tam sim no.
