| Abstract Scope |
Compact, light thermoelectric modules based on thin film legs were prepared using different materials and techniques: (i) 5 Al-doped ZnO (n-type) legs alternated with 5 Ca3Co4O9 (p-type) legs deposited on Al2O3 and silica substrates by pulsed laser deposition (PLD); (ii) 5 n-type and 5 p-type skutterudite legs of the composition Smy(FexNi1-x)4Sb12 (n-type: x = 0.63 and y = 0.20; p-type: x = 0.70 and y = 0.40) deposited on silica substrate by PLD; (iii) 5 ink-jet printed n-type Ag legs alternated with 5 screen-printed p-type PEDOT-PSS legs on photopaper scaffold. Maximum output power of the modules was measured as 16 pW at 300 °C, 0.16 μW at 300 °C and 0.045 μW at 70 °C, respectively. These encouraging results suggest the feasibility of miniaturized thermoelectric modules for powering out-of-the-grid IoT devices in the μW range.
