a Scheme of the fabrication of the micro-scale thermoelectric generator by DLP-based optical printing. (Scale bar: 5 mm) To fabricate the thermoelectric generator, the p-type Cu2S legs were initially patterned and heat-treated at 723 K, and then the n-type SnSe2 legs were patterned and annealed at 573 K. b Output voltages and powers of the micro-scale thermoelectric generator at various temperature differences. c Plots of output voltage and power density as functions of temperature difference. The blue dashed, and red dashed lines were fitted by a linear fitting of the output voltage and a second-order polynomial fitting of output power, respectively.
