Take it to the limit: a story of piezoelectric materials and devices for extreme conditions

Video
Prof. dr. Andrew J. Bell
The University of Leeds, United Kingdom
Andrew J. Bell is a professor of electronic materials at the University of Leeds, School of Chemical and Process Engineering. In 2011 he founded Ionix Advanced Technologies Ltd. to exploit the new high temperature piezoelectric compounds emerging from his research group. He has published over 200 papers and received several awards from the field of materials science.

This presentation will tell a 20-year long story of how a curiosity-driven, ferroelectric materials research topic developed into a 2 million dollar professional association business, manufacturing industrial ultrasound transducers based on modified BiFeO3 piezoelectric ceramics for use under extreme conditions (above 500 °C). On that journey, from undergraduate project through to industrial manufacturing, we discovered some interesting materials science, we learnt how to process materials on the edge of instability, and we overcame our academic sensitivities in order to finance a spin-out company and followed some unexpected paths to gain moderate commercial success. The talk aims to provide a contemporary and perhaps idiosyncratic view of both the science and business of piezoelectric materials.
