High-tech lifesaver

SCIENTISTS have created a smartphone signal-blocker that stops drivers getting distracted behind the wheel.

Created by car giant Nissan, the Signal Shield uses 19th century technology to solve a 21st century motoring problem.

A secure flip-top signalblocking compartment in the car’s armrest can store mobile phones and block out all cellular, Bluetooth and wi-fi signals. It works on the “Faraday cage’’ principle – developed 180 years ago by English scientist Sir Michael Faraday.

The ‘‘cage’’ is made of a conductive material, such as wire mesh, which blocks electromagnetic fields. The prototype has been developed and tested in the UK by Nissan on one of its Juke sports utility vehicles. It has been praised by motoring groups.
