PiezoMEMS is an exciting new technology area that supports many rapidly growing markets, with applications in inertial sensing, resonators, RF switches and energy harvesting amongst others. NPL has an internationally leading position in measurement science and technology to support these applications, particularly in tackling one critical challenge - that of using MEMS technology to match the measurement spatial resolution for direct piezoelectric measurements, to the length scales of these developing technologies.

This webinar will focus on the industrial measurement requirements for emerging PiezoMEMS technologies and the barriers faced by product developers in establishing online metrology for quality assurance in high volume commercial applications. The development of a MEMS-based tool for the d33 parameter will be presented, which provides a unique capability to accurately evaluate the functional properties of piezoelectric materials in micro-scale materials.

The webinar will be of interest to researchers and applications engineers looking to develop or simulate micro-scale piezoelectric functional devices, to those developing instrumentation, and to those developing piezoelectric materials.

This event will be led by Dr Jenny Wooldridge and Professor Markys Cain:

Dr Jenny Wooldridge is leading work on developing new metrological techniques to measure piezoelectric properties at the microscale using Microelectromechanical Systems (MEMS). She is also developing test systems to look at coupling in magnetoelectric composites using interferometry, and has previously worked on projects to model the piezo- and pyro-electric charge response in small-scale devices.

Professor Markys Cain's current interests follow development of characterisation methods for the performance related properties of electroceramics including ferroelectrics, piezoelectrics, magnetoelectrics (multiferroics) and related materials. Understanding the origins and character of electro-mechanical and magneto-electrical coupling that exists in these materials down to the atomic scale is an important part of this. Read bio
