Embodiment 1

[0017] A flexible and elastic electrode is composed of spandex elastic fiber and silver-plated alloy nylon 6 fiber fabric. The silver-plated alloy fiber contains 40% silver and 4% indium. It is woven into a flexible and elastic fabric by knitting or weaving, so that elastic fibers and silver-plated alloy fibers are connected as a whole. The electrode is in the shape of an arm ring, which can be placed on the arm of the human body and used to detect the surface myoelectricity of the human body. Surface EMG is the neuromuscular bioelectrical signal recorded from the surface of the human skin through electrodes. Myoelectricity is the result of bioelectricity generated by the excitation of human muscles and nerves. The action potential of muscle movement is indirectly detected on the skin surface through volume conductors such as muscle tissue, subcutaneous tissue, and skin. The detection of human bioelectricity must rely on the guidance of electrodes, but not all electrodes ma...

Embodiment 2

[0019] A flexible and elastic electrode is composed of spandex elastic fiber and silver-plated nylon 6 fiber fabric, and the silver content of the silver-plated fiber is 50%. It is woven into a flexible and elastic fabric by knitting or weaving, so that elastic fibers and silver-plated alloy fibers are connected as a whole. The electrode is in the shape of a small vest that exposes the abdomen. The outside of the small vest-shaped electrode is connected to an external device through a shielded wire, and can be worn on the body for detecting electrocardiographic signals.

Embodiment 3

[0021] A flexible and elastic electrode is composed of spandex elastic fiber and silver-plated nylon 6 fiber fabric. The silver-plated alloy fiber contains 45% silver and 5% indium, and is woven into a flexible and elastic cloth by knitting or weaving, so that the elastic fiber and the silver-plated alloy fiber are connected together. The electrode is in the shape of a headgear, and the outer side of the headgear-shaped electrode is connected to an external device through a shielding wire, and can be placed on a person's head for detecting EEG signals.

Abstract

The present invention discloses a flexible and elastic electrode and application thereof. The electrode comprises elastic fiber and silver alloy plated fiber, the proportion of the elastic fiber and the silver alloy plated fiber is 1:1-50, and the elastic fiber and the silver alloy plated fiber are integratedly connected in a knitting manner. The silver alloy is composed of silver and more than one metal elements selected from tin, zinc, nickel, copper, gold, cadmium, lead, bismuth, indium and gallium. In the silver alloy plated fiber, the silver makes up 10-70% of the fiber weight, and the one metal elements selected from tin, zinc, nickel, copper, gold, cadmium, lead, bismuth, indium and gallium make up 0.01-20% of the fiber weight. The electrode is especially suitable for a wearable device, reliable contact between the electrode and the human skin is ensured, the electrode has the characteristics of low power consumption, low impedance, long service lifetime, high elasticity, high strength, stretching resistance, light weight, small size and good flexibility, the electrode can be bent, folded and washed, is comfortable to wear, convenient use and not easy to be polarized, and is safe and reliable, and long-term monitoring of myoelectricity, brain electricity, electrocardio, heart rate, respiration and body temperature of a human body can be achieved.

Description

technical field [0001] The invention relates to the field of medical care equipment, in particular to a flexible and elastic electrode and its application. Background technique [0002] The existing electrodes for detecting EEG, EKG and EMG are not flexible and elastic. In order to make good electrical contact between the electrodes and the skin to derive potential, it is necessary to apply conductive paste on the skin to reduce the impedance of the electrodes. The conductive paste may damage the skin, or it is not close to the skin and affects the detection accuracy. It cannot be used for the detection of curved parts such as the neck and face, let alone wearable devices. Electrodes made of pure silver wires or silver-plated fibers are easily oxidized and vulcanized, and their resistance increases significantly during use, causing serious problems of inaccurate detection results Contents of the invention [0003] One of the objects of the present invention is to provide ...
