摘要

This work reports thermoelectric generators (TEGs) for portable and wearable self-powered electronic devices. Two kinds of TEGs, including low (device #1) and high (device #2) integrated number of thermoelectric elements, employing a high performance thermoelectric material fabricated by an assembly technology which are evaluated and compared against each other. Device #1 consists of 17 pairs of thermoelectric elements with dimensions of 1 mm x 1 mm x 2 mm while device #2 has 127 pairs of thermoelectric elements with dimensions of 0.4 mm x 0.4 mm x 2 mm. Both devices are fabricated on the same substrate of 15 mm x 15 mm. Maximum output powers for devices #1 and #2 are obtained as 10.1 mW and 33.9 mW at temperature difference Delta T of 75 degrees C, respectively, while at low.T = 5 degrees C, those of devices #1 and #2 are 43 mu W and 91 mu W, respectively. Fabricated TEGs show higher performance in comparison to the recent related works. Moreover, the harvested energy from the fabricated TEG can be stored in a rechargeable battery via a DC-DC converter. The output of the DC-DC converter reaches 2.8 V and 4 V at Delta T = 2 degrees C and 8 degrees C, respectively, which corresponds to the DC-DC electronic conversion efficiency.DC DC is 8.1% and 23.3%, respectively. The fabricated TEG as a power source for a calculator as well as a twist watch has been demonstrated successfully. The investigation in this work indicated that the fabricated TEG possesses a high potential for portable and wearable self-powered electronic devices.
