The self-charging cellphone

05 March 2010

YOUR cellphone need never again run out of juice while you're on the go. So says Nokia of Finland, which filed a US patent last week for a handset that recharges itself by harvesting energy from the owner's motion.

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, keeping it topped up.

What do you think?

This is just brilliant (The fact that this technology will be used on cellphones). Though I think it would still need to be charged from time to time.

Imagine shaking your cellphone in an inconvenient motion (if you know what I mean). "Oh, I'm just charging my cellphone".

Oh yeah, of course. I imagine you would still need to charge it from time to time. Especially in the early stages of the technology.

Like you though, I like the idea that this technology will be used on phones, because the opportunity exists to expand it into other fields that would benefit so many hand held gadgets such as PDAs, games consoles, Satnav systems and so on.

Is this similar to the Citzen Eco-Drive watch tech? Seems pretty cool, but yeah it would have to be pretty sensitive, maybe more people would take a walk this way though.

I want this!!!!@

People walking (physical activity which is eco friendly and beneficial to our health) charges phones (Eco friendly and really practical).

People should really start to open their eyes and see that the possibility to lead a better life for them and the world has been always there in one form or the other, and is still expanding.

Get fit and charge your phone. Finally a company that cares about customers health.

Charging by kinetic energy is nothing new: I've seen it used for watches and the like. But to power a phone...interesting.

Kantie Panties charged with motion?

Shush. I'll give you this pair of Twisted Panties if you stop leaking our business plans.
