Abstract: An acoustic energy harvesting device that includes a plurality of transducers for the collection of acoustic energy from an acoustic source and for converting the acoustic energy into electrical energy, a plurality of series clusters forming a transducer array, a transducer array panel for holding the transducers, and a back plate. Each transducer has a rectifying circuit for making voltage and current rectified. Each series cluster has a set of transducers connected in series, and the series clusters are connected in parallel such that the voltage and the current derived from the rectified transducers is increased and can be fed into a storage device. The back plate is disposed behind the transducer array such that the back plate creates an amplifying effect by increasing pressure impingement on the transducers such that output of the electrical energy is increased.
