The invention belongs to the field of equipment for measuring
human body impedance and particularly relates to a flexible
electrode for measuring
muscle impedance and a preparation method thereof. The flexible
electrode for measuring
muscle impedance comprises an insulating flexible substrate, at least one pair of exciting
electrode plates, at least one pair of measuring electrode plates,
surface modification layers,
metal leads,
metal lead connectors and a
polymer protective film. The exciting electrode plates and the measuring electrode plates are arranged to form an
electrode array, the
electrode array, the
metal leads and the metal lead connectors are arranged on the insulating flexible substrate, the
surface modification layers cover all the electrode plates, and the face, provided with the
electrode array, of the insulating flexible substrate is covered with the
polymer protective film. According to the electrode, measuring errors caused by contact
interface impedance can be effectively reduced through the insulating flexible substrate and the interface modification
layers, no wound or pain is generated, operation is easy and convenient,
repeatability is achieved, and the electrode is suitable for being popularized.
