Could Future Cameras be Powered by Pressing the Shutter Button?

Researchers in Australia are working on developing a thin piezoelectric film that can be used to convert mechanical energy into electricity. An uber-useful application would be to use the film in existing gadgets, allowing button presses and finger swipes to be used to recharge the device’s battery. One of the lead scientists, Dr. Madhu Bhaskaran, states,

The power of piezoelectrics could be integrated into running shoes to charge mobile phones, enable laptops to be powered through typing or even used to convert blood pressure into a power source for pacemakers – essentially creating an everlasting battery.

Wouldn’t it be crazy if cameras of the future could be powered solely by pressing the shutter button when taking photos (and perhaps other buttons while chimping)?

    Interesting concept – especially useful for people that twitch too, they could spend all day doing nothing but twitching and power their whole house ;)

    Specialize designed clothes with battery packs so we can generate power off of the world’s children at play.  A clean renewable resource. =-)  And it doesn’t require unsightly wind towers, massive solar arrays, or smoke stacks.

    If piezoelectrics could solve those problems, I would think they would have been used for this long ago.  It looks like too much money spent chasing after too little energy.

    I wonder how efficient piezoelectric tech is, to allow this to be possible.
