February 20, 2025 – Thermoelectric materials can convert temperature differences into electrical voltage and vice versa. They are used, among other things, for the thermal management of a range of electrical devices. However, their efficiency is often limited and production is also quite expensive. Researchers from the Austrian Institute of Science and Technology of Austria (ISTA) have now developed a new method for 3D printing high-quality, sustainable thermoelectric materials. Their findings were recently published in Science under the title ‘Interfacial bonding enhances thermoelectric cooling in 3D-printed materials’ (DOI: 10.1126/science.ads0426).
