Abstract
ⶠPresent work shows design, fabrication and functional characterization of a very low cost energy autonomous, maintenance free, flexible and wearable micro thermoelectric generator (μTEG). ⶠThe preliminary prototype integrates an array of 100 thin films thermocouples of Sb2Te3 and Bi2Te3. ⶠAt real operation conditions (thermal gradient of 15 °C), device generates an open circuit output voltage of about 160 mV, electrical output power up to 4.18 nW. ⶠDeposition investigation of Sb2Te3 and Bi2Te3 thin films alloys on Kapton HN polyimide foil by RF magnetron co-sputtering technique is discussed. ⶠDeposition parameters have been optimized to gain perfect stoichiometric ratio and high thermoelectric power factor.
