2. Conversion principle
2.1 Resonant systems
Energy recovery from mechanical vibrations is based on the use of a resonant inertial system with a natural frequency equal to or close to that of the excitation to which the system is subjected. There are usually three families of generators :
resonant generators with speed-proportional damping ;
resonant generators with a damping force having a constant amplitude opposite to the displacement;
parametric generators...
