  • 13. Measuring d33 - Pitfalls and Best Practice Advice: Dr. Markys Cain

- In this webinar, we take a metrological deep dive into the complications surrounding the measurement of the piezoelectric charge coefficient d33 and present ways of circumventing them.


  • 14. Textured Piezoelectric Ceramics - Relationship between Processing and Properties: Dr. Mark Fanton and Dr. Gerald Stranford 

In this webinar, we will discuss the connections between processing, preferred microstructure alignment and the electro-mechanical properties of textured piezoelectric ceramics, focusing mainly on the Mn-doped PMN-PZT material family. The engineering challenges associated with each step of the manufacturing process to yield tailored properties will be outlined and linked to the ability to control the process in a repeatable fashion. We will discuss performance parameter and material trade-offs for both transmit and receive applications.
