a Schematic diagram and real picture of the module. b Output voltage. c Output power versus output current to the i-TE generator module with the ΔT of 5, 10, and 15 K. The i-TE gel and electrode of the module are PVA-1.5/0.25 M CuCl2/CaCl2 gel and Au@CP, respectively. d Powering the thermohydrometer with no additional voltage booster when harvesting a ΔT of 20 K. e Voltage generated from the i-TE capacitor module when harvesting a temperature difference of 15 K. The i-TE gel and electrode of the module are PVA (15 wt%)− 0.03 M CuCl2 gel and CP, respectively. f Demonstration of thermal voltage generated by a 9-cell capacitor module from a cup with warm water.
