Page 22: Research news on Smart sensing metamaterials
Smart sensing metamaterials integrate engineered micro- and nano-structured media with sensing, communication, and actuation functions across acoustic, optical, electromagnetic, and mechanical domains. Work in this area spans metamaterial-enabled wave control, metasurfaces, and auxetic or lattice architectures combined with MEMS, e-skins, and e-textiles to monitor physiological signals, structural integrity, and environmental conditions. These systems often employ flexible, printable, or biodegradable platforms, multiplexed readout, and self-powered operation to enable distributed, real-time, and unobtrusive measurement in wearable, industrial, underwater, and aerospace applications.
