Charging the battery of a wireless mouse by moving it... Is it possible?

Would it be possible to make a wireless mouse that gets its battery charged by moving it around? The motion we make with it could be turned to energy... Would be possible/feasible? Has some company produced this already?

Or taken further, could typing on a keyboard be a source of energy for your laptop?

This is a bit based on the idea of energy producing by movement like from waves or from sidewalks.

  • Jun 21 2011: The concept exists, i.e generating electricity by movement. I guess Simon is referring the the link I have pasted below.

    To answer your question, yes, it may be possible to generate a mouse that self charges, however, the amount of electricity produced will not be sufficient to charge a laptop. I guess the application would be to extend the battery life rather than replace it completely.

    An excellent idea, i hope this does get implemented.

      Thanks, thats been driving me mad all day :)

    Jun 21 2011: There are technologies already developed that could do this I think. I'm struggling to remember the name, but there is a type of material that when compresses/stressed produces an electric feild that can be used to draw a current. They have been used before to make self charging watches. I think they could possibly be used to create self charging keyboards and mice but I doubt the power output would be sufficient to power the laptop itself.

    I also read an article some time ago that was talking about using the same technology in buildings near busy roads to draw some of the buildings electricity from the vibrations caused by passing cars.

    Here is what I was referring to when I stated that the concept exists. Hope this helps...

      Jun 24 2011: This is an interesting mechanism using stress or strain cells. It is designed for smaller, remote applications like pacemakers or insulin disposal system but it can definitely be scaled to this device.

      On the other hand there are simpler, more cost effective solutions like a dynamo adapted for this purpose or using inertia as they would be more commercially viable as well. (Shake to Recharge). It requires power in the order of a few milliwatts which I don't think a stress or strain cell can produce.

      The novelty here is clearly the application than the supporting system.

    Jun 23 2011: Its a brilliant idea, if it is not out there yet. Developing it also should not be too much of a hassle as it involves simple electronics and electro-mechanical parts. To my understanding, the commercial viability is noteworthy and definitely the way forward.
  • Jun 22 2011: Proper application of the technology found in Kinetic watches might work well for this idea.
