Harvesting vibrations from heartbeats
Shown in the images above: (a) current pacemaker and (b) future leadless pacemaker powered by energy harvesting
French researchers at CEA-Leti and the Sorin Group are developing a low-power cardiac pacemaker (5µW instead of 25 µW in current pacemakers), powered by mechanical energy from a patient’s own heart beats.
The objective is to eliminate the need for batteries, which must be surgically replaced every six to ten years in conventional pacemakers, and to develop a cardiac stimulator eight times smaller than conventional designs from 8 cm3 to 1 cm3. Such miniaturization would allow for the attachment of the pacemaker directly to the epicardium. Fully functional prototypes should be manufactured by the end of the year. The industrialization is expected within five to ten years, after validation tests and agreements from health administrations.

Very interesting ideas. It would be good to see them commercialised.

Ann-Francoise, great article...would you be interested in expanding it to a short book chapter for the energy harvesting book I am editing? kris.iniewski@gmail.com

Energy harvesting seems to be one of the next big thing in 2013. I wonder whether the energy is being harvested is actually needed elsewhere. Harvesting from breathing and body heat would probably has no side effect to the person. I would like to understand more about "Harvesting vibrations from heartbeats", etc.

The amount of energy harvested thru these methods is ridiculously small except for the green wheel. You're better off putting a rechargable watch battery into devices along with wireless charging circuitry than use these methods. The exception being research into implantable pacemakers that never need removing.

In olden days, human energy was used for various purposes.We had slaves at that time :)
