AI Insight
Researchers developed a flexible material using eutectic gallium-indium (EGaIn) liquid metal that simultaneously provides infrared camouflage and harvests thermal energy through thermoelectric effects. The material can dynamically control its infrared radiation signature while converting temperature differences into electrical power, combining two functions that are typically separate. The EGaIn-based system maintains flexibility and functionality across varying temperatures and mechanical deformations.
Why it matters
This dual-function material could enable new wearable technologies, adaptive thermal management systems, and military applications requiring both thermal camouflage and energy harvesting. The flexible nature makes it suitable for integration into clothing, robotics, and portable devices where rigid materials would be impractical.
