Bonjour,

avez-vous vu cet article qui présente une source d'énergie d'1 cm3 ?

Scientists at the University of Southhampton have successfully  
developed a minuscule generator that powers devices in lieu of  
batteries, especially in cases where a battery replacement procedure  
is next to impossible. It will first be tested on wireless sensors  
before being moved into more important areas such as powering heart  
pacemakers. According to test results, this new generator is 10 times  
more efficient than similar devices, despite measuring less than a  
cubic centimeter in size. It works by utilizing vibrations around it  
to make magnets on a cantilever in the confines of the device to  
wobble, and thus generating power. Guess this would make a great self- 
powered medical implant if the need ever arises.
