A self-charging cloth and a method for generating electricity using the same, relating to the field of wearable devices. The self-charging cloth comprises a frictional electric generator part (10) and a capacitor part (20) that are woven together, the frictional electric generator part (10) being used for converting mechanical energy generated when a human body moves into electric energy and outputting an electric signal, and the capacitor part (20) being used for storing the electric signal outputted by the frictional electric generator part (10). By means of the self-charging cloth and the method, by using a soft wearable cloth, mechanical energy generated when a human body moves can be converted into electric energy, and the electric energy is saved, thereby achieving continuous charging for a wearable electronic device.
