a A weaved TE textile with waterproof layer washed in water. b Schematic of a TE textile harvesting thermal energy in an out-of-plane direction. The pitch waves correspond the segment length to realize successive p-n junctions alternate between hot and cold surfaces. The carriers flow in same direction along the fiber to multiply the voltage. c–e TE performance of a single p/n TE pair, a single fiber with 8 p/n TE pair and a TE textile weaving by 33 TE fibers in out-of-plane direction under different temperature differences between the substrate and the ambient.
