Here, we have gathered all of our webinar episodes for you to watch or rewatch.
- An introductory session for those interested in learning about the electromechanical fundamentals of piezoelectric ceramics.
- This episode explores the various technologies enabled by the direct and converse piezoelectric effect.
- In this episode, key design principles for immersion and contact type ultrasonic transducers are reviewed.
- An examination of the use of High-Intensity Focused Ultrasound (HIFU) in dermatologic therapy and cancer treatments.
- A sneak peek of several innovative piezoelectric technologies that enable for instance miniaturization, MEMS-integration and flexible substrate compatibility.
- This episode examines the current state and future prospects of lead-free piezoceramics as well as the restrictions imposed on lead-containing electronics by the ROHS-directive.
- In this webinar, we will examine the coefficients of the piezoelectric matrix, exploring how each of them can be determined, and how they are affected by factors such as temperature, time and frequency. Furthermore, we will provide instructions on how to establish a rudimentary finite element analysis model for use in dedicated FEM software such as COMSOL.
- Here, we take a deep dive into the functionality of piezoelectric actuators, highlighting the strengths and limitations of various designs as well as their ideal applications.
- Professor Vincenzo Esposito from DTU - Technical University of Denmark presents the latest development in the field of oxygen-defective metal oxides and their potential for actuation. Furthermore, we explore recent progress in the additive manufacture (3D printing) of piezoelectric ceramics.
- Dr. Klaus Brebøl, managing director of Limiel España SL, offers best practice advice for establishing viable simulation models for piezoelectric devices in SPICE and finite element software.
- 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.
- 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.
- 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.
