The invention discloses a flexible thermoelectric fiber based on a braided P-N structure and a preparation method thereof. The flexible thermoelectric fiber includes textile fibers, and the textile fibers are in a sinusoidal structure, and the peaks or troughs of the sinusoidal structure include P type thermoelectric region and N-type thermoelectric region, a conductive region is provided at the junction of the P-type thermoelectric region and the N-type thermoelectric region, and the conductive region is located at the endpoints of the crest and the trough of the sinusoidal structure, that is, the conductive region is located at the apex of the wave crest , at the lowest point of the wave trough. The preparation method of the flexible thermoelectric fiber prepared by the invention is simple, low in cost, and easy for large-scale production; the thermoelectric structure and the woven structure are combined together, which has good flexibility, air permeability and durability, and has wider application prospects. |
