We report here global simulations and designs of mechanical structures able to recover power over a large spectrum below 100 Hz. Contrary to existing structures tuned on a particular frequency, we have investigated conversion structures with low quality factors allowing power scavenging with a high electrical damping. MATLAB and Mathematica analytical models have been performed to determine the mechanical and electrical parameters that maximize the scavenged power for a wide number of applications. An electrostatic transduction is used to convert vibrations of the moving mass into electrical power.
