Abstract

The invention relates to a bio-electrical signal sensor and a method using the sensor for manufacturing an electric signal collecting device. The sensor comprises an electrode tip provided with columnar tubes and a connecting body, an electrode body provided with a cavity, and electrolytes. A sealing part is arranged at the upper end of the cavity. An electrode is communicated with the electrolytes. The electrode tip is made of a flexible material. Electrolyte permeation cores with tiny holes are arranged in the middles of the columnar tubes. The manufacturing method for the collecting device comprises the steps that the electrical signal sensor is installed, and one ends of supporting bands penetrate into connecting holes in fixing blocks; or furthermore, multiple signal electrical signal collecting devices are combined to form a combined type electrical signal connecting device matched with an organism. The bio-electrical signal sensor has the advantages that the sensor is reasonable in structure and easy to manufacture, and the electrode tip can be replaced; as the porous permeation cores mutually independent are arranged in the middles of the flexible columnar tubes of the electrode tip, the electrode makes good contact with skin, electrode impedance is stable, the measurement precision is high, and wearing comfort is improved.
