Northumbria University design graduate Will de Brett has redesigned the everyday electrical plug, making it pin-less and stackable to accommodate numerous devices.
Mi Plug uses wireless charging to transfer electricity between the wall socket and plug, while both are fully encased in plastic.
This means there are no exposed metal contacts as in traditional AC power plugs, making the design much safer and easier to handle.

It is fully waterproof ? so much so it could be used underwater ? and there are no holes where children might be tempted to stick their fingers.
The disc-like plug simply slots into a matching depression in the wall outlet or charger. The plugs can also stack on top of each other, allowing a single socket to power up to eight devices with reduced clutter.
"This project is a response to the existing plug not tackling fundamental flaws such as bare pins, which can be a serious shock hazard," said de Brett.
"For the last 70 or so years, the way we've consumed power has changed radically. The devices we use have changed from being big and power-hungry appliances to small, energy-efficient, portable devices," he continued.
"With most of the electronics in the modern home being these small devices, it seemed strange to be powering them with heavy, cumbersome plugs."

Mi Plug was a runner-up in the UK heats of the James Dyson Award, which recognise the best in student design and engineering, as well as the John Lewis Design and Inn...
