Magnetic-powered chips explored in research project

Wireless technology being researched is different to wi-fi

A group of European researchers are working to develop silicon chips that forego wires and carry electric currents, an advance they say could lead to computers that run up to 500 times faster than today’s models.

The nanotechnology being used, dubbed inverse electron spin resonance, relies on firing electrons into magnetic fields produced in tiny semiconductors.

“We can only go so far in getting more power from silicon chips by shrinking their components,” says Alain Nogaret of the University of Bath’s Physics Department.

Universities and research centres in Nottingham, Leeds, Scotland, Belgium and France are also involved in the three-year project, which kicks off in October.

The project is based on research from Nogaret published last year.

While computers are said to double in power every 18 months, Nogaret and his team argue that the rate isn’t sustainable, given the limitations of electric wiring, which can lead to weakened signals between components at high speed.

The wireless technology being developed by the project is different than other wireless technology, such as wi-fi, which requires components too large for use on individual microchips.

Wireless semiconductors could become reality five to ten years after the project finishes, the researchers say.

Among the benefits of the newfangled chips would be that they could be programmed to reroute signals in the event of failures, something that wired systems cannot do so well, the researchers say.
