The Energizer Bunny will no longer have to beat his drum around pacemaker owners

Researchers in the UK are developing a series of pacemakers that run on heat that is produced from body movement.  The device will use micro generators that produces electricity whenever the pacemaker owner moves.

This technology allows for a great step in medical advancement by reducing the number of surgeries a pacemaker patient has to go through roughly every 10 years for battery replacement.  Researchers claim the technology has not been perfected yet, but it will be a more reliable power source because it runs off of the power generated by the human body.  

However, don't expect new devices to use the technology exclusively.  New devices will likely still rely on battery power and simply offset power usage with the microgenerator instead. It may be decades before microgenerators become primary power sources for pacemakers, and even then devices will likely still have some sort of emergency battery source.

The cost of the research project is around £1 million, about the equivalent to $1.96 million.  The departments and companies involved in the research include the Department of Trade and Industry and Zarlink Semiconductors.  

There is no word yet when these devices go into testing or expected approval dates. According to the BBC, the research is moving along quite well.

Gotta love wikipedia... wonder if it can be effectively used to rewrite history ie. make the South win the war etc. :-)

Seems both company's have Bunny's as Mascots.

Sorry we came down on you so hard, OP

I wonder, what exactly is it that they're beating these days??? ;)

Let's all just hope Sony isn't involved with this. Sizzle, pop, whoosh!

No there are no worries there, this definitely is not the Sony solution.

That is a proprietary solution being developed for release in 2009 (expected in stores around 2025) that involves the addition of approx 67 electronic and piping components to the human body and renders the heart superfluous entirely. (Sony executives are said to already be trialing them).

Hmm, your heart still beats, and your diaphragm still moves. Or it should.....unless your undead! At that point though, a pace maker is moot.

The devices will still have batteries....

Well, the emergency battery source is common sense (something goes wrong with the heat generator). That should be included on ALL pacemakers and medical devices that are implanted in bodies.


How bout this instead?

Instead of this, why not make microgenerators that are inserted into the main arteries around the heart and produce power similiar to hydro-electric dams. Have minature generators that are spun by the flow of blood through the body. A limitless supply of power unless the person dies. The only issue is 1) will clots cause an issue here and get caught in the spinning part and 2) can you make it so blood doesn't leak out.

I don't know if something like this is possible, but if it is, it seems like a pretty good idea to me.

Probably not a viable option. HBP is enough of a worldwide problem as it is, a hydroelectric damn in ur blood vessel is bound to make it worse, not to mention the hell it would do in the case of a blood clot.

Two research projects
By nineball9 on 12/29/2006 8:30:38 AM , Rating: 2
"... pacemakers that run on heat that is produced from body movement." seems to be a combination of two areas of research, which is not what the article states. The first research project mentioned only involves body motion (kinetic energy).

"Other research teams" are working on using body heat as an energy source. Curious how this approach would work; the second law of thermodynamics requires a temperature differential for heat engines (work from heat). Perhaps one side of the device would be closer to the patient's skin and thus be cooler, but that's just a guess.

Absolutely. First it's for pacemakers, but soon the machines will be harvesting our bio-electricity for themselves!


Heart powered iPod charger!!

Heart powered iPod charger will be great!

you have a simple surgery to inergrate this generator to your heart and voila~! you have a permanent 3.6 V power source sticking out your heart you never ever need to recharge your iPod again just plug and play!!

Checkout Duracell's site in Turkey. That mascot looks like a bear to me. Plus, it isn't pink.
