Abstract EN
A new incus-body driving type transducer relying on piezoelectric stack, with broad frequency bandwidth, is proposed for use in a middle ear implant.
To aid the design process of this transducer, a coupling biomechanical model of the human middle ear and the piezoelectric transducer was established by reverse engineering technology.
The validity of this model was confirmed by comparing model predicted motions with experimental measurements.
Based on this verified biomechanical model, the main parameters of the transducer were determined.
And its power consumption was calculated.
Finally, to verify the capability of the designed piezoelectric transducer, a human temporal bone experimental platform was built.
And the dynamic characteristics and the stimulated performance of the piezoelectric transducer were tested.
The result showed that stapes displacement stimulated by the transducer excitation at 10.5 V RMS was equivalent to that from acoustic stimulation at 100 dB SPL, which is an adequate stimulation to the ossicular chain.
The corresponding power consumption is 0.31 mW per volt of excitation at 1 kHz, which is low enough for the transducer to be used in a middle ear implant.
Besides, this transducer demonstrates high performance at high frequencies.
