[45] It may be seen from the above examples and comparative examples that a part of expensive silver and silver chloride material are replaced by a low-priced nano- carbon conductive material, which not only reduces the cost, but also the prepared electrode sheets have low impedance and may completely satisfy the use requirements.
However, when the using amount of nano-carbon material is too high, the alternating current impedance 1s too large to satisfy the use requirements.
[46] The silver-carbon-silver chloride paste of the present invention is supplied to listed companies such as INTCO MEDICAL TECHNOLOGY CO.,LTD, the impedance of the prepared electrode sheets is 1000 Q or below, and the properties satisfy the use requirements of the electrocardiogram detection electrode.
[47] What is mentioned above is merely preferred embodiments of the present invention, it should be noted that those of ordinary skill in the art can also make several improvements and embellishments without departing from the principles of the present invention, and all the improvements and embellishments will also fall within the scope of protection of the present invention.
