The Ionix mission is to create value for our clients by facilitating process operations and measurement in extreme environments.

Ionix has created a range of proprietary high performance piezoelectric materials that can operate in high temperature environments, and that enable sensors, actuators and transducers which address applications and markets not accessible to existing piezoelectric devices.

The Leadership Team


David Astles

David is a business leader with wide experience gained in a major blue chip – Shell – and leading small company start-ups. He has a strong international sales and marketing background with a track record of launching new products and technologies in global markets, covering a wide range of industry sectors including chemical process, oil and gas, lubricants, mining and refining.


Tim Comyn
Technical Director

He received his Ph.D. degree in 1997 from the University of Leeds, UK and holds M.Sc. and B.Sc. degrees in chemistry from the University of Bristol, UK. His research interests have included ceramic processing, preparation, and characterization of single crystals and ferroelectric thin films; actuator design and prototyping; and the use of synchrotron and neutron radiation to study stress, phase, and magnetic structure. Tim is responsible for the development of next generation piezoceramic materials.


Tim Stevenson
Development Director

Tim was a Senior Research Fellow at the University of Leeds, since completing his Ph.D in 2010, specialising in high-temperature piezoelectric metrology, and the design of extreme environment sensors. He has experience of leading European development programmes and was awarded Gold and the title of “Early Research Career Engineer” at Westminster in 2011 for impact on UK research. Tim is now responsible for the development of next generation extreme environment devices. In 2019 Tim was elected Fellow of the Institute of Materials, Minerals and Mining.
