The development of thermoelectric devices provides an ideal solution for self-sustaining Internet Things (IoT) applications. However, existing face issues such as low integration levels and poor stability. To address these challenges, this paper presents a novel method fabricating flexible using Ag2Se/MgAgSb, which combines MEMS lithographic lift-off techniques to achieve precise control over the dimensions functional layer while also reducing fabrication costs. optimal cell were identified through simulations. device achieved open circuit voltage 0.49 mV at temperature difference 50 K. Additionally, output power density Ag₂Se/MgAgSb Y-type reached 3.39 µW/m² 5 demonstrated excellent flexibility; even after being bent 800 times around glass rod with diameter 4 mm, its conductivity decreased by only 12%. Furthermore, it maintained stability under high humidity conditions. This work offers strategy miniaturization large-area controllable reliable devices, well enhancement in their reliability.
