Abstract
An electromechanical generator comprising an electromechanical device for converting mechanical vibrational energy into electrical energy, the electromechanical device being a velocity damped resonator having a damping coefficient and a resonant frequency, a power detector for detecting the output electrical power from the electromechanical device, a controller, and a damping coefficient adjuster for adjusting the damping coefficient of the electromechanical device, the controller being arranged to control the damping coefficient adjuster in response to the output electrical power detected by the power detector.
