Preparation and Characterization of Piezoelectric Materials

点击翻译按钮获取中文摘要

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. **
