Thermoelectric generators (TEGs) enable direct conversion of heat into electricity without the need for moving parts. Among thermoelectric materials, Bi2Te3 and its alloys have been reported to have excellent thermoelectric performance at low temperatures (200-400 K) and are suitable for energy harvesting applications within space and nuclear systems. We use solvothermal methods to synthesize high purity Bi2Te3- based nanomaterials with fine control over material composition, crystal dimensions, and electrical properties that can be readily dispersed into an ink for additive manufacturing of flexible TEGs. This work demonstrates the development of flexible and high performance TEGs using multiple additive manufacturing methods, including screen printing, aerosol jet printing, and plasma jet printing. The low cost and scalable additive manufacturing methods developed in this work demonstrates a significant advancement in the field of thermoelectrics toward commercially viable technology for energy harvesting and remote sensing devices.
