Problems solved by technology

[0003] The main purpose of the present invention is not only to solve the problem that the hair affects the electrode contact, but also to solve the situation that the existing dry electrode will drift in the potential of the electric signal, and the contact area between the ring frame contact element and the skin will be affected by the skin. The fluctuation of the surface affects the problem of electrical signal transmission

Abstract

The invention discloses a comb electrode. A signal processing unit is electrically contacted with a life body. The comb electrode comprises an electrode plate and a plurality of electrode posts, wherein the plurality of electrode posts are convexly arranged on the electrode plate and comprises at least one main electrode post and at least one reference electrode post; and the plurality of electrode posts are electrically connected with the signal processing unit. Therefore, during the electric signal transmission on the main electrode posts, reference potentials (levels) of the reference electrode posts are compared, so that the aim of reducing the level drift error is fulfilled.

Description

technical field [0001] The invention relates to an electrode, especially a comb-shaped electrode that can be grouped and stretched. Background technique [0002] The existing electrode patch used to measure physiological signals on the human body, in order to reduce the impedance of the metal sheet on the electrode patch in contact with the skin and improve the measurement quality of the signal, a layer of conductive glue is usually applied on the skin to make it conductive The glue penetrates into the subcutaneous of the human body and moistens the skin to increase the conductivity of the electrode patch. However, some parts of the human body have hair distribution, and this measurement mode through the conductive glue is easily affected by the barrier of the hair, and in the amount After the test, the conductive adhesive will often cause trouble in the cleaning of the testee, or for some testees with sensitive skin, it will cause skin allergies. Therefore, some relevant pe...
