Preparation and Characterization of Piezoelectric Materials

这笔赠款将提供设备，以准备和表征压电材料和设备，并将形成UBC的新铁电实验室（FEL）。这些工具所实现的工作的最初重点将是用于传感应用的压电纸。该设备将允许对纸进行极化并表征其压电/电致伸缩特性。这些能力对于优化这种纸基片的制造工艺以实现上级传感器性能将是重要的。** 设备包括用于面外电晕极化和面内接触极化的工具。它还包括一个直接压电系数仪和一个匡威压电系数仪，以确定样品的压电性能，以及一个半自动系统，用于在纸样品上丝网印刷电极。**

This grant will provide equipment to prepare and characterize piezoelectric materials and devices and will form UBC's new Ferroelectricity Laboratory (FEL). The initial focus of the work enabled by these tools will be on piezoelectric paper for sensing applications. The equipment will permit poling the paper and characterizing its piezoelectric / electrostrictive properties. These capabilities will be important to optimize the fabrication process of such paper substrates to achieve superior sensor performance. ******The equipment includes tools for out-of-plane corona poling and for in-plane contact poling. It also includes a direct piezoelectric coefficient meter and a converse piezoelectric coefficient meter to determine the piezoelectric properties of samples, as well as a semi-automatic system for screen-printing of electrodes onto the paper samples. **
