Apple iPhone ‘could be charged by the human heart’

“The human heartbeat could be used to power an ipod after scientists developed a tiny chip which uses the body’s own movement to generate power. Scientists hope that as the nanotechnology used in the chip evolves, it could lead to electronics which don’t require batteries or mains power,” The Telegraph reports. “Hailed as a milestone, it can use tiny movements such as the pinch of a finger to generate power.”

“The team, presenting their findings at the National Meeting & Exposition of the American Chemical Society, have used it to power LCD displays and diodes, as well as to transmit a radio signal once its generated power has been stored,” The Telegraph reports. “Dr Zhong Lin Wang, of Georgia Institute of Technology said: ‘This development represents a milestone toward producing portable electronics that can be powered by body movements without the use of batteries or electrical outlets. Our nanogenerators are poised to change lives in the future. Their potential is only limited by one’s imagination.'”

The Telegraph reports, “Five nanogenerators working together produced about 1 micro ampere output current at 3 volts about the same voltage generated by two regular AA batteries. Dr Wang said: ‘While a few volts may not seem like much, it has grown by leaps and bounds over previous versions of the nanogenerator. Additional nanowires and more nanogenerators, stacked together, could produce enough energy for powering larger electronics, such as an iPod or charging a cell phone.'”

  1. I think the main thing is… where the heck is this nanogenerator inserted? or placed? Someone mentioned pacemaker and that would be a real good idea to have this charge the pacemaker instead of some bulky device.. but who knows.

  2. So many things to address here:

    1. The iPhone currently (no pun intended) requires 5 volts in the range of 1 amp (can be more or less, which controls charging time). So, they would need to get the nanogenerators up to 5 volts, and then stack hundreds of them to charge an iPhone. Maybe some day.

    2. Scientists research many different areas where we don’t yet know what is possible. Believe it or not, many of the very useful things we use EVERY DAY are based on research that, at the time, didn’t seem as practical as other work being done. A diverse mix of immediately-useful development and long-range basic research is what builds a dynamic, advancing civilization. Don’t waste OUR time by crying out against basic research and attempts to push the frontiers of tech. Nuclear fusion is NOT easy, but many scientists are working on it (and even a guy in Brooklyn is doing homebrew fusion research in his basement). I doubt much money is being spent on reflectors in space to modify climate change. Whatever is learned from that research will be useful for other things anyway, even if never used to control Earth’s climate.

    3. Finally, if you read about “science” in the Telegraph or the Daily Mail (or almost ANY publication that isn’t focused on science), you must realize that the reporter is almost certainly doing a terrible job representing a realistic picture of what the science/tech can do, how soon it can do it, and the motivations and intentions of the scientists. The reporter wants a story that will cause excitement and/or controversy, so they will tweak whatever is said to be as extreme as possible. Don’t buy into it. Just imagine if a reporter did a story on something in your life – do you really believe that you wouldn’t read the story and say “Wow, this guy’s a wacko/loser/hero”? If not, the reporter wasn’t doing his/her “job” – writing a story that gets hits to earn ad revenue.
