Figure 11. Schematic potential profile of (A) gelatin/KCl, (B) gelatin/(Fe(CN)₆^3-/Fe(CN)₆^4-), and (C) gelatin/(Fe(CN)₆^3-/Fe(CN)₆^4-)/KCl i-TEs. (D) Schematic illustration of diffusion, redox reactions, and interaction of various ions in gelatin/(Fe(CN)₆^3-/Fe(CN)₆^4-)/KCl i-TE at a ΔT. (E) The fractional contribution of each effect to α in gelatin/(Fe(CN)₆^3-/Fe(CN)₆^4-)/KCl i-TE. (F) V_oc of the i-TE in quasi-continuous charging-discharging at a ΔT = 8.5 K for 100 cycles. (G) Power, voltage, and current during the fifth discharging in (F). (H) Voltage and current during discharging at a ΔT = 8 K with R_load = 5 kΩ. (I) Power as a function of discharging time using different R_load. (J) V_oc of 25 i-TEs connected in series worn on hand at a ΔT = 10 K. (K) Power, voltage, and current of the device in (J).
