High frequency polymer-based ultrasonic transducers are produced with electrodes thicknesses typical for printed electrodes obtained from silver (Ag) nano-particle inks. An analytical three-port network is used to study the acoustic effects imposed by a thick electrode in a typical layered transducer configuration. Results from the network model are compared to experimental findings for the implemented transducer configuration, to obtain a better understanding of acoustical effects caused by the additional printed mass loading. The proposed investigation might be supportive of identification of suitable electrode-depositing methods. It is also believed to be useful as a feasibility study for printed Ag-based electrodes in high frequency transducers, which may reduce both the cost and production complexity of these devices.
高频聚合物基超声换能器是采用银（Ag）纳米颗粒油墨制成的典型印刷电极厚度生产的。使用一个分析型三端口网络来研究典型分层换能器配置中厚电极所施加的声学效应。将网络模型的结果与所实现的换能器配置的实验结果进行比较，以更好地理解由额外印刷质量负载引起的声学效应。所提出的研究可能有助于确定合适的电极沉积方法。它也被认为作为高频换能器中基于印刷银电极的可行性研究是有用的，这可能会降低这些设备的成本和生产复杂性。
