Flexible thermoelectric generators (f-TEGs) prepared by printing technology are gaining increasing interests due to the advantages of material saving, structure flexibility and ease of fabrication. Despite their low power output (uW – mW), f-TEGs are highly suitable for massive wearable or environment-deployed IoT devices. To establish a thermoelectric energy harvester, the output electricity from the f-TEG needs to be regulated by a voltage-boosting electronic circuit. In this study, we demonstrate a modular thermoelectric TEG consisting of multiple dispenser-printed f-TEG modules. Each single TEG module can provide an electric power of 10s uW at a delta T of 10 – 20 K. A modular platform is designed to boost the output power for practical applications by integrating multiple f-TEGs. The technical issues regarding printing materials, sintering, thermoelement geometry optimization and contact electrode selection are discussed. The influences of various environment scenarios on the output performance of the modular f-TEG are evaluated.
