Electronics are becoming smaller and more powerful, yet managing the heat they generate remains critical. Funded by the European Innovation Council, the SPARK-e project aims to tackle this issue by focusing on innovative materials called solid-to-solid phase-change materials (PCMs). These materials can absorb and store large amounts of heat during phase transitions, making them ideal for advanced thermal management. Researchers will develop thermal switches to control heat flow, and energy-harvesting systems that turn heat into electricity. By combining experiments and simulations, SPARK-e will bridge the gap between nanoscale heat behaviour and real-world applications. Targeting technology readiness level 4, SPARK-e aims to enhance heat dissipation and reduce energy consumption in nanoelectronic devices.
