Resumen

RESUMEN

Un estudio comparativo de la impedancia de un polímero tipo poliolefina termoplástica elastómera con un electrodo comercial gelificado universal ha sido hecho con el fin de determinar si el polímero puede ser usado como electrodo seco para la adquisición de señales cardiacas. Los resultados de la espectrometría de impedancia mostraron características muy parecidas y que ambos se comportan como dispositivos resistores, por ejemplo a 120 Hz el polímero registró una resistencia de 6,3 k y el electrodo comercial 7,2 k . Además, se obtuvo una relación lineal de corriente contra voltaje, determinando resistencias de 7 k y 8,2 k para el polímero y electrodo comercial gelificado respectivamente. Finalmente concluimos que es aplicable el uso de este polímero en electrodos secos.

Palabras clave: Electrodos, polímeros, poliolefina termoplástica elastómera, electrocardiograma, espectroscopia de impedancia.

ABSTRACT

A comparative impedance study of a polymer type Thermoplastic Polyolefin Elastomer with a commercial universal gel electrode has been made in order to know whether the polymer can be used as dry electrode for the acquisition of cardiac signals. The results of the impedance spectroscopy showed very similar characteristics and that both devices behave as resistors. For instance, at 120 Hz the polymer measured a resistance of 6,3 k and the commercial gel electrode 7,2 k . Further, it was getting a linear relation of current versus voltage, determining resistances of 7 k and 8,2 k for the polymer and commercial gelled electrode respectively. Finally we have concluded that the polymer is applicable to construct dry electrodes.

Keywords: Electrodes, polymer, thermoplastic polyolefin elastomers, electrocardiogram, impedance spectroscopy.
