1. A preparation method of a stretchable inorganic thermoelectric thin film comprising the following steps:
synthesizing AgxSn1-xSe solution by a solution process where X is a decimal number greater than 0 and less than 1;
forming a thermoelectric thin film by coating the AgxSn1-xSe solution on a substrate;
forming a physically separated pattern on the thermoelectric thin film;
forming a patterned thermoelectric film by electrically connecting each pattern;
encapsulating the patterned thermoelectric thin film;
transferring the encapsulated patterned thermoelectric thin film to an elongated stretchable substrate; and
removing a tensile force from the elongated stretchable substrate.
