    Abstract: The electrode structure for measuring a bio-signal and an apparatus for measuring an electrocardiogram using the same are disclosed. The electrode structure for measuring a bio-signal, comprises an electrode pad to measure bio-signals based on capacitive coupling between the electrode pad and human skin; an absorption layer formed at one side of the electrode pad; and a preamplifier which is electrically connected with the electrode pad and filters noise from the bio-signals from the electrode pad and amplifies and outputs the signals. Thus, the initial noise stabilization time can be reduced, and stable electrocardiogram signals can be obtained quickly without noises.

    Abstract: Disclosed is a method for separating nickel powders and cobalt powders from each other in a mixture of nickel powders and cobalt powders. The method includes a first step of heating a mixture of nickel powders and cobalt powders received in a container to a temperature of 350° C. to 500° C.; and a second step of reacting the heated mixture with a magnet to separate the nickel powders and the cobalt powders from each other, wherein in the second step, not the nickel powders but the cobalt powders react with the magnet, and thus the cobalt powders move out of the container and thus are separated from the nickel powders.
