Abstract

The invention discloses a creature body surface electric signal detection method for reducing temperature errors. The creature body surface electric signal detection method comprises the following steps: dividing array electrode points on an electrode carrier into four regions; performing whole sealing encircling by using printing circuit wires as ground wires of 2-3mm respectively; arranging electric heating wires in parallel among electrode rows in the four regions; after an electrode substrate enters into a state to be tested, performing scanning detection on a first electrode signal of each row on the substrate through a single chip microcomputer; after scanning is completed, acquiring the maximum value Vm, and calibrating scanning on the electrode points one by one, wherein a calibration equation is provided. By adopting the creature body surface electric signal detection method, other introduced errors such as contact resistance, humidity variation and external interference can be counteracted by virtue of temperature drift errors, and thus the detection errors can be minimized.

Description

technical field [0001] The invention relates to a method for using a detection electrode array suitable for weak electrical signals on the surface of a biological body, in particular to a method for detecting electrical signals on the surface of a biological body that can reduce temperature errors. Background technique [0002] The detection of electrical signals on the surface of living organisms has always been one of the difficult problems in the field of biomedicine. The detection of electrical signals on the surface of living organisms has the following problems: [0003] 1. The signal amplitude is very weak, such as nerve potential, electromyographic signal, etc., which cannot be directly obtained by conventional detection methods and equipment. If the amplifier is introduced, it will bring great interference and make the original signal characteristics be submerged by noise signals. [0004] 2. Most of the acquisition of existing bioelectrical signals uses microelect...
