Abstract: This work introduces a metamaterial (MTM)-integrated space-time coding (STC) transmitting array to detect the multitarget vital sign signals including respiration and heart rates (HR). A ...

In a new Nature Physics publication, University of Amsterdam researchers introduce human-made materials that spring to life. These 'metamaterials' don't just learn to change shape, but can ...

Researchers from IMDEA Materials Institute, in collaboration with China's Nanjing and Huazhong Universities, have developed a new acoustic metamaterial capable of transmitting complex sound signals ...

A 3D-printed piezoelectric metamaterial uses topology-driven charge transport to locate underwater sound sources from a single compact transducer, replacing bulky hydrophone arrays. (Nanowerk ...

Neurophos, a startup company based in Austin, Texas, that is working on photonic chips based around metamaterial optical modulators, says it raised $110 million in a series A round of venture funding.

Metamaterials with stiffness tunability have demonstrated great potential in mechanical systems that operate in variable environments. Real-time stiffness visualization, which translates the stiffness ...

Metamaterials – artificially made materials with properties that aren’t found in the natural world – are poised to transform daily life. Their unique properties are enhancing products from sporting ...

The age of smart, self-optimizing materials has begun. A programmable metamaterial has been developed that shatters the limits of old material science. US researchers at the University of Connecticut ...

The Wave Engineering for eXtreme and Intelligent maTErials (We-Xite) lab, led by engineering assistant professor Osama R. Bilal, has developed a reconfigurable metamaterial that can control sound ...

Why are Metamaterials Unlike Anything in Nature? Material properties are typically defined by electric permittivity (ε) and magnetic permeability (μ), with free space representing the baseline values ...
