Chinese scientists have announced the development of a so-called “smart surface” that can harvest electrical energy directly from electromagnetic radiation, potentially turning radar and communication signals into a power source.
The system integrates communications technologies with electromagnetic engineering, positioning it for use in next-generation 6G networks, intelligent stealth applications, and advanced electronic warfare scenarios. By enabling simultaneous wireless data exchange and energy collection, the design represents a shift toward multifunctional, self-powered systems.
Conceived as an all-in-one platform, the smart surface combines sensing, communication, and autonomous power generation, allowing it to perform complex tasks while maintaining resistance to jamming and signal disruption. According to the research team, the technology could have far-reaching implications for 6G, IoT ecosystems, and intelligent stealth capabilities.
The researchers argue that continued development could unlock more capable robotic and autonomous systems, improving efficiency, reliability, and coordination across networked platforms.
In military aviation, the concept envisions stealth aircraft that not only minimize radar exposure but actively exploit incoming radar waves as both an energy source and a communication medium. This dual-use approach could enhance survivability while improving data exchange across formations.
Beyond aircraft, the architecture could support future satellite systems by enabling self-powered sensors, micro base stations, and integrated relay networks. The team noted that such designs may ultimately enable environment-adaptive sensing and communications systems with minimal external power requirements.
