The invention relates to a method for extracting action potential features based on multiple wavelet transformation. The single wavelet can not comprehensively describe the action potential at present. The method comprises the following steps: extracting wavelet features on a wavelet basis with Db, Sym and Bior wavelets as a basic wavelet transformation function, respectively detecting componentsof each group of wavelet features according to KS detection rules, calculating the weighted coefficient of each feature component through dimensionality reduction of high dimensional feature space, selecting three groups of feature components to synthesize an original confederate matrix, and obtaining a weighted confederate feature under multiple wavelet transformation through multiplying the original confederate matrix by a weighted matrix. The method of the invention overcomes the simplicity and limitation of the single wavelet feature description and combines multiple wavelet features. Therefore, the method can express the specific feature components of the action potential and the fused confederate features after weighting more effectively, and can also realize more comprehensive and effective expression of the signal features.
