Claim:
1. A cochlear implant, comprising: a transducer; and at least one cochlear electrode attached to auditory nerve; wherein the transducer further comprising: a plurality of cantilever beams and a piezoelectric piece bonded to each of the cantilever beams; wherein each of the plurality of cantilever beams has a different predetermined natural frequency from each other; each of the plurality of the cantilever beams comprises one free end and one fixed end; the piezoelectric piece is positioned on the fixed end; each of the plurality of cantilever beams is capable of converting incoming acoustic waves to voltage outputs through the piezoelectric piece; wherein the transducer is an energy harvester device having the capability of generating energy therefore reducing the need of battery to power up a cochlear implant; wherein the voltage outputs of the plurality of cantilever beams stimulates the corresponding auditory nerve; and wherein the voltage outputs generated by the piezoelectric piece associated with each cantilever beam vibrating near the natural frequency are higher than a threshold voltage value for stimulating the auditory nerve.
