Abstract
Embodiments of a vibrational energy harvester are provided. A vibrational energy harvester can include a translator layer sandwiched between two stator layers. The translator layer can include a plate having an array of magnets and two or more piezoelectric patches coupled to a tether beam attached to the plate. The stator layers can have a printed circuit board with multilayer electrical windings situated in a housing. In operation, vibration of the housing can result in bending of the piezoelectric patches coupled to the tether beam. This bending simultaneously results in a relative displacement of the translator, which causes a voltage potential in the piezoelectric patches, and a relative velocity between the translator and the stators, which induces a voltage potential in the stator coils. These voltage potentials generate an AC power, which can be converted to DC power through a rectification circuit incorporating passive and active conversion.
