11. Piezocomposites - Properties and Design Optimization via FEM: Charles Mangeot and Wei-Yi Chang
- Examination of the strengths and drawbacks of piezocomposites - a combination of a piezoelectric ceramic and a resin. Properties, ideal applications, design approaches and manufacturing procedures are discussed.
12. Lead-Free Piezoceramics - Viable or Wishful?: Erling Ringgaard and Baltramiejus Andrijaitis
- In this webinar, we examine the current state of the RoHS-directive, as the exempt status granted to lead-containing piezoceramics in certain applications is up for renewal. Subsequently, we explore the potential of currently available lead-free alternatives and present a case study in which the material NTK-KNN was used to design a flowmeter transducer.
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.
