Wearable human motion energy harvester
Jacket with the electrical generator
There is shown in Figure 1.a - set of flat spiral shaped coils, b - location of the inductive elements, c – location of the magnet, d – permanent magnet
Researchers from Riga Technical University, in Latvia, have developed a mechanical energy harvester for generating electricity during human walking. Our device has a planar structure. Electrodynamic converter consists of flat, spiral-shaped coils and a rectangular or an arc-shaped magnet, and all elements can be deployed on a variety of clothing items. During the natural human motions, the generator elements move in relation to one another and induce the pulses of voltage inside the flat inductor.
The prototype was tested with the wearer walking at different speeds of 3, 4, 5 and 6 km/hr which, according to the researchers, corresponds to the slow, normal and quick walking of a middle-aged man.

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 :)

We have a blog about piezoelectric technology being used for human energy harvesting. See "Human Energy" as The Connecting Edge.
