提出了一种基于压电叠堆的新型锤体驱动式换能器，用于中耳植入体。为了辅助该换能器的设计过程，利用逆向工程技术建立了人中耳与压电换能器的耦合生物力学模型。该模型的有效性得到了证实，通过比较模型预测的运动与实验测量。在此基础上，确定了换能器的主要参数。并计算了其功耗。最后，为了验证所设计的压电换能器的性能，搭建了人体颞骨实验平台。并对压电换能器的动态特性和激励性能进行了测试。结果表明，以10.5VRMS的换能器激励所刺激的镫骨位移与以100dBSPL的声刺激所刺激的镫骨位移相当，这是对听骨链的一种充分刺激。相应的功率消耗是在1kHz下每伏激励0.31mW，这对于在中耳植入物中使用的换能器来说足够低。此外，该传感器在高频下表现出高性能。
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.
