Abstract
An improved vibrational energy harvester includes a housing and at least one energy transducer. In an embodiment, a second mass element is arranged to receive collisionally transferred kinetic energy from a first mass element when the housing is in an effective state of mechanical agitation, resulting in relative motion between the housing and at least one of the second and further mass elements. The energy transducer is arranged to be activated by the resulting relative motion between the housing and at least one of the second and further mass elements. In a further embodiment, kinetic energy is collisionally transferred in a velocity-multiplying arrangement from the first to a second or further mass element that has a range of linear ballistic motion. The energy transducer is arranged to be activated, at least in part, by the ballistic motion of the second or further mass element. The energy transducer, or a portion of it, may be attached to the housing, or it may be attached to another of the mass elements.
