Fig. 4

a Voltage generation from one device under ∆T = 8 °C followed by charging/discharging a capacitor. b Linearly increasing voltage with more number of devices connected in series under ∆T = 3.9 and 7.6 °C. The upper inset is the voltage profile as a function of time as 2, 4, 6, and 8 devices were joined in series. The lower inset depicts two devices connected in series. c Voltage and current profiles when the capacitor (470 μF) was hooked up to the digital hydrometer shown in the inset. d Voltage profiles for one module (m1) and two modules connected in parallel (m1 and m2), followed by charging a capacitor (470 μF) as a function of time under ∆T = 7.6 °C. Each module consists of 4 devices connected in series.
