Engineers at Princeton University have developed power-generating rubber films that could use energy from everyday body movements such as breathing and walking to power cell phones, pacemakers and more.

Geez...who the hell thinks up this stuff??
Professors at Princeton.

Pretty nifty stuff. I can see this getting used in a way to harness natural energy. Wind and waves to be particular. Semi depend on the energy it takes to move it: If its like a piece of salt-water taffy or flexible like a bed sheet.

It would also be important to note the power capacity. a few micro volts? maybe even a whole volt?

I have been watching the piezoelectric material advances for years. It is getting closer and closer to being commercially viable for everyday use, and will certainly bring a lot of advances in micro electronics and robotics.

Power generating capacity is defined by the amount of Watts something can generate. Voltage is only half of the equation. P= V * I (where I = current in Amps).

Wikipedia has a very good article on Piezoelectric material if you are interested:

I want numbers. Can it really power a phone just by walking a few steps or do we need to jog kilometers just to talk for a minute.

The tech sounds really cool. All sorts of possibilities for it, but I do have to wonder like this guy...

I know the it says you can fit "up to 100 PZT strips can fit in a millimeter of space", so even if they don't put out a lot of power they don't take up much space. But how many would you need to say keep your cell phone charged? Or an MP3 player charged?

Damn! What now?! While the world is busy fighting the terrorist and the terrorism, good scientist are all busy building good stuff...but are they really good enough for us? This one invention of Princeton University Professor might put everyone in danger...not only he discover it as good as it is, he also put everything in jeopardy specially our world we live now. Oh, well F*** it all! Now, we need to be more carefull than ever...!

Wow. Imagine the factory that produces these things. I worked at a regular RAM factory and am still in shock at how much resources it takes to make them. Could this actually be worth the long term effects such as resource depletion, pollution (from fabrication and disposal), new kinds of cancer or psychological damage to users of this technology? There is a Tesla quote something like, "our technology has surpassed our humanity".
