Abstract Scope |
In recent years, there has been an increasing emphasis on micro-generators, prompting a shift in the development of Bi2Te3-based thermoelectric materials from bulk to thin-film configurations. This trend allows for enhanced flexibility and minimization, opening new possibilities for flexible thermoelectrics (FTEs). FTEs suit to curved heat sources, efficiently recovering waste heat from unconventional and irregularly shaped surfaces. However, the current encapsulation of FTEs may not be durable for long-term use or requires several processes and high-temperature curing, which can harm the materials. Therefore, this study utilizes magnetron sputtering to deposit Bi2Te3-based TEs onto an organic substrate with self-healing properties, creating a self-encapsulated flexible thermoelectric thin film. Besides its flexibility, the encapsulation technique is simple, with temperature control at 50 °C. The material exhibits water repellency, potentially suitable for energy conversion in high humidity or underwater environments. |
