No, not that Chip. AFAIK. ;)


Working with researchers from the National Physical Laboratory and Cambridge-based dielectric antenna company Antenova Ltd, the Cambridge team used thin films of piezoelectric materials, a type of insulator which is deformed or vibrated when voltage is applied. They found that at a certain frequency, these materials become not only efficient resonators, but efficient radiators as well, meaning that they can be used as aerials.The researchers determined that the reason for this phenomenon is due to symmetry breaking of the electric field associated with the electron acceleration. In physics, symmetry is an indication of a constant feature of a particular aspect in a given system. When electronic charges are not in motion, there is symmetry of the electric field.
Symmetry breaking can also apply in cases such as a pair of parallel wires in which electrons can be accelerated by applying an oscillating electric field. "In aerials, the symmetry of the electric field is broken 'explicitly' which leads to a pattern of electric field lines radiating out from a transmitter, such as a two wire system in which the parallel geometry is 'broken'," said Sinha.
The researchers found that by subjecting the piezoelectric thin films to an asymmetric excitation, the symmetry of the system is similarly broken, resulting in a corresponding symmetry breaking of the electric field, and the generation of electromagnetic radiation.

I like that site. Chock full of "addicting info".

WIK gave them the idea for it.

Well, we all know he met every single member of the team involved.

Met them? Hell, they are his children.

They've already built one for 160m. It's the only chip ever manufactured that takes up an entire city block.

That's a lot of fractatting.

I guess I shouldn't hold my breath for the 136 Khz chip to become available. :mrgreen:

Great, cell phones will get even smaller and sound even tinnier. I'm already looking at buying a pair of superwide sunglasses for driving and a "Jitterbug" cell phone for this deaf old fart! :irked:

They call that Cleveland.

The size curve has already started to swing the other way. I might have considered a Note, if I didn't use my phone for running already. But lugging around a standard Galaxy-sized phone is enough.

Running a Lumia 1520 6" phablet myself. Gotten quite used to the large size.

But anyway, the antenna thing is interesting. Or... not.

Hopefully, as far as mobile phones are concerned, this means that they can make phone antennas betters instead of putting up bigger and stronger towers everywhere.
