Nokia Files Patent For Self-Charging
Smartphone That Never Needs To Be Charged
Small, battery-powered gadgets make powerful computing portable but unfortunately, there's still a continual need to recharge the batteries of phones and other gadgets by hooking them up to a tangle of wires.
Fortunately the latest technology trends proposed a way to cut the cords by wirelessly supplying power to devices and Nokia researchers have developed a new technique for powering mobile devices that could draw enough power from ambient radio waves or kinetic energy to keep a smartphone topped up.
Nokia has filed a US patent application for a phone that can work continuously without requiring to be plugged into a wall socket for a recharge, just buy a phone, signing up for a good data plan and enjoy in unlimited freedom because you’ll newer need a charger again, sounds great isn't it?
If you ask me, this is a major step toward a portable, adaptable and cost-effective technology for powering mobile devices and it's not as far-fetched as it may seem.
Nokia envisages a phone in which the heavier components, such as the radio transmitter circuit and battery, are supported on a sturdy frame. This frame can move along two sets of rails, one allows it travel up and down, the other side to side.
Strips of piezoelectric crystals sit at the end of each rail and generate a current when compressed by the frame. So as the user walks, or otherwise moves the phone, the motion generates electricity. This charges a capacitor which in turn trickles charge into the battery.
