Made of pure copper, the ultra-thin ‘shell’ conceals sensors from remote inspection while still allowing them to probe the exterior environment
A team of researchers from the National University of Singapore (NUS) has invented a novel camouflage technique that effectively hides thermal and electronic sensors without compromising performance. Led by Assistant Professor Qiu Cheng-Wei from the Department of Electrical & Computer Engineering at NUS Faculty of Engineering, the team created the world’s first multifunctional camouflage shell that renders sensors invisible in both thermal and electric environments.
Current technologies which make sensors ‘invisible’ usually also make them ineffective, while others only work in specific physical fields (i.e. either thermal or electrical). Over the past ten months, the NUS team has experimentally demonstrated that they could hide sensors in both thermal and electric fields without them being detected. The invisible sensors are also able to continue to probe on the environment while ‘under cover’.
Asst Prof Qiu explained, “We have designed a camouflage ‘shell’ that not only mimics surrounding thermal fields but also electric fields, both at the same time. The object under camouflage becomes truly invisible as its shape and position cannot be detected in terms of both thermal and electric images.”
