➀ Researchers have developed a novel hybrid material that doubles thermoelectric efficiency by separating heat and electrical charge transport.

➁ The hybrid material combines an alloy of iron, vanadium, tantalum, and aluminum with a bismuth-antimony mixture, forming a compact structure that enhances energy conversion.

➂ This breakthrough could lead to more efficient energy harvesting in miniaturized electronics, especially for IoT devices, offering both performance and cost-effectiveness.
