Synopsis: Energy: Energy colaterale: Metamaterial:

Its energy harvesting capabilities come courtesy of a metamaterial a synthetic material engineered with characteristics not found in nature like the ability to bend light the wrong way

In this case the microwave-harvesting metamaterial that acts kind of like a solar panel converting microwaves into up to 7. 3 volts of electricity enough to charge small electronics.

and sound energy harvestingâ#according to Duke graduate student Alexander Katko one of the inventors. â##Until now a lot of work with metamaterials has been theoretical.

It is essentially a single-sensor listening system that combines acoustic metamaterials and compressive sensing techniques. ifferent from previous research efforts that generally rely on signal

our proposed method is a unique hardware-based approach by exploiting carefully designed acoustic metamaterials,

he device with a compact array of resonant metamaterials is demonstrated to distinguish three overlapping and independent sources with 96.67%correct audio recognition,

Each magnet within the new metamaterial is shaped like a grain of rice and roughly 63 nanometers in length.

tailored phase transitions could enable metamaterials to be adapted specifically for different needs in future, "explains Heyderman.

but with its adaptability, this new metamaterial could be the wave of the future. Apart from facilitating information transfer,

2015materials/Metamaterials Molecular trick alters rules of attraction for nonmagnetic metals August 5th, 2015yolks and shells improve rechargeable batteries:

This week in the journal Applied Physics Letters("Metamaterial electromagnetic energy harvester with near unity efficiency"),researchers from the University of Waterloo in Canada report a novel design for electromagnetic energy harvesting based on

"This involves the use of metamaterials that can be tailored to produce media that neither reflects nor transmits any power--enabling full absorption of incident waves at a specific range of frequencies and polarizations."

"Classified as a metamaterial because it displays properties that have yet to be found in nature,

tailored phase transitions could enable metamaterials to be adapted specifically for different needs in future, "says Heyderman.

the so-called metamaterial exhibits phase transitions, much like those between steam, water and ice. This effect was observed by a team of researchers headed by Laura Heyderman from PSI."

the result of the new study also reveals that the PSI researchers'metamaterial would be a potential candidate here.

Thanks to a special measuring technique, the scientists initially studied the collective magnetic behaviour of their metamaterial at room temperature.

When the researchers cooled the metamaterial gradually and constantly, however, they reached a point where a higher order appeared:

tailored phase transitions could enable metamaterials to be adapted specifically for different needs in future, "explains Heyderman.

Besides its potential use in information transfer, the metamaterial might also prove useful in data storage or for sensors that measure magnetic fields.

and therefore the properties of the metamaterial, can only be conducted exclusively at PSI. The equipment at the S S,

The device is an'acoustic metamaterial a structure patterned with smaller features and designed to affect the acoustic waves that pass through it.

It fits the definition of a metamaterial, a class of structures first realized at UC San diego 15 years ago that is beginning to be expoited for potential practical use."

which endow them with several advantages compared to traditional metal-based metamaterials. The key advantages include enormous degree of tunability, relatively low losses,

"We have demonstrated now an entirely new class of electromagnetic metamaterials that are fabricated from separate atomic planes of Van der waals materials,

"Electromagnetic metamaterials are revolutionizing imaging and sensor technologies. Since the initial demonstration these systems have advanced already to practical applications."#
