In this project, tunable piezoelectric resonator concepts will be explored for use in frequency control and electromechanical filter applications. The centerpiece of the research is a technique for tuning piezoelectric resonators through the use of shunt capacitance. This concept can be particularly useful in applications in which mechanical resonators are used as frequency sources (including electronics and radio frequency communications applications) and in electromechanical filtering. In order to fully exploit increasing the resonator frequency, maximizing the tuning range and quality factor, and understanding the temperature-frequency characteristics of the resonator. This proposal presents a three-year research plan to address these and other issues. The impact of the research will be made through the generation and dissemination of knowledge that will be pertinent to the frequency control community. The research will also have impact through the training of students. In addition to graduate students, undergraduate and high school students will involved in the project through a new diversity initiative at the University of Pittsburgh called the Pitt Engineering Career Access Program.

在这个项目中，可调压电谐振器的概念将探讨用于频率控制和机电滤波器的应用。 研究的核心是通过使用并联电容调谐压电谐振器的技术。 该概念在机械谐振器用作频率源的应用（包括电子和射频通信应用）和机电滤波中特别有用。 为了充分利用提高谐振器频率，最大化调谐范围和品质因数，并了解谐振器的温度-频率特性。 该提案提出了一项解决这些问题和其他问题的三年研究计划。 研究的影响将通过产生和传播与频率控制社区相关的知识来实现。 这项研究还将通过对学生的培训产生影响。 除了研究生，本科生和高中生将通过匹兹堡大学一项名为皮特工程职业准入计划的新的多样性倡议参与该项目。
