Abstract
The present invention relates to an energy harvesting apparatus capable of converting small magnitude low frequency vibrational energy into useful electrical energy that may be stored and used to power microelectronic devices and rechargeable battery technologies. The energy harvesting apparatus utilizes a piezoelectric device coupled to a pneumatic controller for modulating the vibrational energy received from vibrational energy source into a useful alternating energy waveform. A rectifier is further coupled to the piezoelectric device for converting alternating electrical energy to direct current energy for supporting associated external circuitry.
