Abstract: Conventional thermoelectric generators (TEGs) are normally hard, rigid, and flat. However, most objects havecurvy surfaces, which require soft and even stretchable TEGs for maximizing efficiency of thermal energy harvesting. Here, soft and stretchable TEGs using conventional rigid Bi2Te3 pellets metallized with a liquid alloy is reported. The fabrication is implemented by means of a tailored layer-by-layer fabrication process. The STEGs exhibit an output power density of 40.6 μW/ cm2 at room temperature. The STEGs are operational after being mechanically stretched-and-released more than 1000
