Currently Jonathan is concerned to build a team to develop reliability engineering science to enable the prediction of electrical component/system reliability under harsh operating conditions. The science that underlies analysis and modelling of component/system reliability is still in its infancy. Most ageing models are a collection of equations generally describing a system from a phenomenological perspective and are limited mainly to that specific system under examination. This has generated a vast array of ageing models based on many different physical principles with many different variables. From an engineering perspective this approach has been adequate within specified limits. However, Jonathan is concerned to develop the physics of component ageing from a fundamental thermodynamics approach and thus develop a generalised theory of ageing (or importantly system robustness) from the bottom upwards.

Three facilities are under development in this research at Heriot-Watt:-

  • The 3D X-Ray Computer Tomography Facility is to aid defect analysis to better understand the physics of failure of electrical and electromechanical devices.
  • The High Current Test Facility is to aid the understanding of degradation processes in high current connectors and wiring in electrical vehicles.
  • The GreenGlean Research Facility uses the micro-systems fabrication facilities within the School to build a suite of macro-systems manufacturing tools for fundamental research of novel materials for energy converter devices.
