Preparation and Characterization of Piezoelectric Materials

这笔赠款将提供制备和表征压电材料和装置的设备，并将形成不列颠哥伦比亚大学新的铁电实验室(FEL)。由这些工具实现的工作的最初重点将是用于传感应用的压电纸。该设备将允许对纸张进行抛光并表征其压电/电致伸缩性能。这些能力对于优化此类纸张基材的制造工艺以实现卓越的传感器性能非常重要。*该设备包括用于面外电晕极化和面内接触极化的工具。它还包括用于确定样品的压电性的直接压电系数计和逆压电系数计，以及用于将电极丝网印刷到纸样品上的半自动系统。**

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. **
