EGaIn Material Offers Infrared Camouflage and Thermoelectric Energy Harvesting
Integrated infrared camouflage materials capable of energy harvesting and sensing hold great potential for enhancing operational efficiency in military settings. A key challenge, however, lies in achieving such multifunctionality without complex fabrication processes. In this study, we address this issue by introducing eutectic gallium‑indium (EGaIn) as a versatile material that combines infrared camouflage with thermoelectric sensing.

Eutectic gallium-indium (EGaIn) has been developed as a versatile material combining infrared camouflage with thermoelectric energy harvesting, addressing the need for multifunctional military technologies without complex fabrication. EGaIn exhibits strong infrared camouflage by reflecting ambient radiation, concealing thermal signatures. It also generates voltage from small temperature gradients, enabling self-powered physiological monitoring. This material offers pathways toward military technologies that integrate concealment with signal transmission. The study highlights EGaIn's potential for self-powered, real-time monitoring of body temperature and breathing patterns, demonstrating its utility in advanced applications.
The development of EGaIn material for infrared camouflage and thermoelectric energy harvesting presents a novel approach to creating advanced military technologies with integrated concealment and self-powered sensing capabilities.
