Abstract: A method is for making a thermoelectric generator device. The method may include forming bottom contacts on a first substrate, and forming a polymer layer over the first substrate with recesses therein, the recesses being over the bottom contacts. The method may include forming a semiconductor material fluid in the recesses of the polymer layer to define thermoelectric couples coupled to the bottom contacts, forming top contacts adjacent a second substrate, and positioning the second substrate so that the top contacts are coupled to the thermoelectric couples.
