An energy harvesting apparatus includes an inverse frequency rectifier structured to receive mechanical energy at a first frequency, and a solid state electromechanical transducer coupled to the inverse frequency rectifier to receive a force provided by the inverse frequency rectifier. The force, when provided by the inverse frequency rectifier, causes the solid state transducer to be subjected to a second frequency that is higher than the first frequency to thereby generate electrical power. The coupling of the solid state electromechanical transducer to the inverse frequency rectifier is a non-contact coupling.
