Abstract
An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator comprising a housing, an electrically conductive coil assembly fixedly mounted in the housing, a magnetic core assembly movably mounted in the housing for linear vibrational motion along an axis, a first biasing device, mounted between the housing and the magnetic core assembly, adapted to apply a centering force acting to oppose movement of the magnetic core assembly away from a central position on the linear axis and a second magnetic biasing device adapted to provide a compensating force to compensate for variations in the centering force of the first biasing device due to temperature.
