The invention relates to a method and a device for detecting blink motions, a readable storage medium and an electronic device. The method comprises: sampling signals output by a plurality of body movement detection chips used for detecting blink actions; when a voltage value of a sampling point of any body movement detection chip is larger than a first threshold, according to sampling point dataof each body movement detection chip in a preset duration from the moment corresponding to the sampling point, respectively determining actual values of various blink characteristic parameters corresponding to each body movement detection chip; aimed at each body movement detection chip, matching the actual values of a target blink characteristic parameter group corresponding to the body movementdetection chip with ideal values of the group of target blink characteristic parameters corresponding to each body movement detection chip; when proportion of the number of successfully matched body movement detection chips and the total number of the body movement detection chips is larger than or equal to a second threshold, determining that a subject has a blink motion. Therefore, real-time property and accuracy of a detection process can be guaranteed, and applicability is wider.
