University of Sussex researchers have developed a more energy-efficient alternative to transmit data that could potentially replace Bluetooth in mobile phones and other tech devices. With more and more of us owning smart phones and wearable tech, researchers at the University of Sussex have found a more efficient way of connecting our devices and improving battery life. Applied to wearable devices, it could even see us unlocking doors by touch or exchanging phone numbers by shaking hands.

Professor Robert Prance and Professor Daniel Roggen, of the University of Sussex, have developed the use of electric waves, rather than electromagnetic waves, for a low-power way to transmit data at close range, while maintaining the high throughput needed for multimedia applications.

Bluetooth, Wifi, and 5G currently rely on electromagnetic modulation, a form of wireless technology which was developed over 125 years ago.

Computers, cars, mobile phones, toasters: countless everyday objects contain microchips. They’re tiny, unremarkable and cheap, but since the outbreak of the coronavirus pandemic, they’ve been at the center of a political and industrial tug of war.

Against the backdrop of the trade war between China and the US, “The Microchip War” spotlights all the aspects of this conflict. In the film, the world’s most influential actors in this industrial sector weigh in.

This feature used to be a niche product for a select group of users, primarily frequent air travelers. But now, with technology being more affordable, it has become more vividly seen in many of the current market offerings. Take Apple’s AirPods Pro or AirPods Max, for example, or Sony’s WH 1,000 XM5 or WF 1,000 XM5 series or, say, the Bose Quite Comfort series. There are many options, from affordable to expensive ones, and the ANC performance varies across the price range.
