ECG Electrode Hydrogel

Cov khoom no yog kev kho mob - qib conductive hydrogel tshwj xeeb tsim los rau kev soj ntsuam cov teeb liab bioelectrical. Nws siv lub moj khaum hydrophilic polymer network uas muaj cov tshuaj electrolyte ntau, nthuav tawm cov ionic conductivity zoo heev (txog ~ 160 S / m). Qhov no tso cai rau kev sib kis tau zoo thiab ruaj khov ntawm cov teeb liab bioelectrical los ntawm daim tawv nqaij mus rau electrode sensor. Cov hydrogel yog mos thiab muaj cov ntsiab lus dej siab (tshaj 80%), ua kom muaj kev sib haum xeeb ntawm daim tawv nqaij thiab txo cov tawv nqaij zoo - electrode interface impedance. Qhov no ua kom pom tseeb thiab ruaj khov ECG teeb liab tau txais nrog qhov tsis tshua muaj waveform distortion thiab lub teeb liab zoo heev - rau - suab nrov piv (tshaj 28 dB). Cov khoom lag luam muaj biocompatibility zoo, yog maj mam thiab tsis{12}} khaus rau ntawm daim tawv nqaij, tuaj yeem hnav rau lub sijhawm ntev, thiab tsis muaj qhov seem thiab tsis mob thaum tshem tawm.
