Abstract: A manufacturing method of an electronic diaper is to provide a sensor feeding band or box supplying a diaper body with a sensor which will be in advance attached on the upper or the lower dry layer of the diaper body for carrying out a sequent process of automatically manufacturing an electronic diaper. The electronic diaper includes an upper and lower dry layer and an sbsorbing layer sandwiched between the two dry layers, a sensor attached on the upper or the lower dry layer. The sensor has a connecting member for connecting with a controller. Sensing the diaper body wetted, the sensor will give a signal to the controller which will immediately give out warning signals to remind a nurse that the diaper is wet and needs to be replaced with a new one so that a user may feel comfortable in using the electronic diaper.
