Thermoelectric power generation is a technology that converts heat into electricity. Conventional thermoelectric devices are driven by the Seebeck effect, but the durability and mechanical flexibility of the devices are limited due to the complex device structure. Recently, thermoelectric devices based on transverse thermoelectric effects have been investigated to overcome these limitations. Artificially tilted multilayer (ATML) is one of the transverse thermoelectric materials, and SmCo₅/Bi_0.2Sb_1.8Te₃ (BST)-based ATML was reported to exhibit excellent transverse thermoelectric conversion performance around room temperature. In this study, we fabricated and demonstrated the flexible transverse thermoelectric device using SmCo₅/BST-based ATML.
