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.

Electric 'nose' can smell when your food's gone bad

Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. ...

Tiny chip could help cameras spot hidden details

A tiny new chip could give cameras and sensing systems a far sharper view of the world, helping them detect subtle differences in materials and environments that standard color imaging systems cannot see.

Sonar–camera system sees through murky waters

For remotely operated underwater vehicles, cloudy and turbulent waters are often a no-go. When vehicles settle on the seafloor or dig through a sand bed, they can kick up clouds of sediment that make it tough for onboard ...
